Main Characteristics of MATLAB
C.1 History
MATLAB was primarily developed by Cleve Moler in the 1970s as an interactive system to access two library subroutines: LINPACK and EISPACK, which are designed for linear and eigenvalue systems. The software gained popularity through word of mouth and was rewritten in C in the 1980s to enhance functionalities, including added plotting routines. The establishment of The MathWorks Inc. in 1984 marked MATLAB's official commercialization and further development.
Notable contributors to MATLAB's origin alongside Cleve Moler include J. H. Wilkinson, George Forsythe, and John Todd. Additionally, LINPACK's authors, such as Jack Dongara, Jim Bunch, alongside Moler, played vital roles. Following these advancements, LAPACK emerged as a successor designed to replace LINPACK and EISPACK.
C.2 Strengths
MATLAB has several strengths: it can function either as a basic calculator or a robust programming language. Its seamless integration of calculations alongside graphical plotting capabilities makes it user-friendly. Interactively interpreted, MATLAB allows for easy error fixes, and it is optimized for fast matrix operations. Furthermore, MATLAB does incorporate some object-oriented programming features.
C.3 Weaknesses
Conversely, MATLAB is not suitable as a general-purpose programming language like C, C++, or FORTRAN. It is primarily tailored for scientific computing, thus not serving well for unrelated applications. Due to its interpreted nature, it is generally slower than compiled languages. MATLAB's command structure is unique, resulting in limitations when trying to translate commands from other programming languages.
C.4 Competition
In terms of competition, Mathematica stands out as MATLAB's chief rival in symbolic computation, excelling in symbolic manipulations favored by physicists. However, MATLAB remains the go-to for numerical analysis and linear algebra, particularly in engineering contexts. Other notable competitors include Scilab, GNU Octave, and Rlab, which vie for similar scientific computing tasks.

Developed primarily by Cleve Moler in the 1970βs.
- Derived from FORTRAN subroutines LINPACK and EISPACK, linear and eigenvalue systems.
- Developed primarily as an interactive system to access LINPACK and EISPACK.
- Gained its popularity through word of mouth, because it was not officially distributed.
- Rewritten in C in the 1980βs with more functionality, which include plotting routines.
- The MathWorks Inc. was created (1984) to market and continue development of MATLAB.
- According to Cleve Moler, three other men played important roles in the origins of MATLAB: J. H. Wilkinson, George Forsythe, and John Todd. It is also interesting to mention the authors of LINPACK: Jack Dongara, Pete Steward, Jim Bunch, and Cleve Moler. Since then another package emerged: LAPACK. LAPACK stands for Linear Algebra Package. It has been designed to supersede LINPACK and EISPACK.
Detailed Explanation
MATLAB was initially developed in the 1970s by Cleve Moler. It was based on existing mathematical subroutines known as LINPACK and EISPACK, which handled linear algebra and eigenvalue problems. Originally, MATLAB was created as an interactive tool to help users access these subroutines without requiring deep programming knowledge. The software spread through informal channels, gaining popularity among users before it was formally marketed. In the 1980s, MATLAB was significantly improved when it was rewritten in the C programming language, adding new features like graph plotting. In 1984, The MathWorks Inc. was established to promote and continue developing MATLAB. Key contributors to MATLAB's development include notable figures in mathematics and computational sciences.
Examples & Analogies
Think of MATLAB's development like the evolution of a smartphone. Just as early smartphones borrowed features from earlier mobile phones and personal digital assistants to create a more interactive and powerful device, MATLAB took inspiration from established mathematical algorithms and made them more accessible to users, effectively becoming a powerful tool for engineers and scientists.

MATLAB may behave as a calculator or as a programming language.
- MATLAB combines nicely calculation and graphic plotting.
- MATLAB is relatively easy to learn.
- MATLAB is interpreted (not compiled), errors are easy to fix.
- MATLAB is optimized to be relatively fast when performing matrix operations.
- MATLAB does have some object-oriented elements.
Detailed Explanation
MATLAB is versatile; it can act like a simple calculator for straightforward calculations but also function as a full-fledged programming language for more complex tasks. One of the key advantages of MATLAB is its ability to easily perform calculations and visualize them through plotting, making it user-friendly. Learning MATLAB is generally perceived as easier compared to other programming languages, partly because of its straightforward syntax. Since it is an interpreted language, users can execute commands one at a time and quickly identify errors, making debugging more manageable. Furthermore, MATLAB is particularly efficient in handling matrix operations, which are prevalent in mathematical computing, and it incorporates some object-oriented programming concepts, enhancing its flexibility.
Examples & Analogies
Consider MATLAB as a Swiss Army knife for numerical computing. Just as a Swiss Army knife has different tools for various situationsβlike scissors, a screwdriver, and a bottle openerβMATLAB provides tools for calculations, plotting graphs, and manipulating matrices, all in one package. This versatility makes it suitable for both casual and advanced users.

MATLAB is not a general-purpose programming language such as C, C++, or FORTRAN.
- MATLAB is designed for scientific computing and is not well suitable for other applications.
- MATLAB is an interpreted language, slower than a compiled language such as C++.
- MATLAB commands are specific for MATLAB usage. Most of them do not have a direct equivalent with other programming language commands.
Detailed Explanation
While MATLAB has many strengths, it also has limitations. It is not a general-purpose programming language like C, C++, or FORTRAN, so it's not ideal for applications outside scientific computing, such as web development or mobile app creation. Additionally, being an interpreted language means that MATLAB programs generally run slower than those written in compiled languages like C++, which can be a downside for performance-critical applications. Furthermore, the commands in MATLAB often do not correspond directly with commands in other programming languages, which can make it challenging for those who are used to different programming environments to transition smoothly to MATLAB.
Examples & Analogies
Think of MATLAB akin to a specialized power tool, like a drill. While it excels at drilling holes (scientific calculations), it may not be effective for tasks like cutting wood or hammering nails (other programming tasks). Just as a drill won't replace a full toolbox, MATLAB cannot replace all programming environments, especially for general software development.

One of MATLABβs competitors is Mathematica, the symbolic computation program.
- MATLAB is more convenient for numerical analysis and linear algebra. It is frequently used in the engineering community.
- Mathematica has superior symbolic manipulation, making it popular among physicists.
- There are other competitors: Scilab, GNU Octave, Rlab.
Detailed Explanation
MATLAB faces competition from several other software products. Mathematica is a well-known competitor that specializes in symbolic computation, which allows for manipulations of mathematical expressions in a way that is more intuitive than numerical calculations. While MATLAB is favored in engineering fields due to its strengths in numerical analysis and linear algebra, Mathematica is often preferred by those in physics for its advanced symbolic analysis capabilities. Additionally, there are open-source alternatives like Scilab, GNU Octave, and Rlab, which offer varying degrees of functionality similar to MATLAB, often without the associated costs.
Examples & Analogies
Imagine a popular restaurant that serves a specialized menu (like MATLAB for numerical computations) but has competitors like a bistro that offers unique dish experiences (like Mathematica with its symbolic manipulation) and food trucks that provide free samples of similar flavors (like the open-source alternatives). Customers will choose based on their specific needs, dietary preferences, or budget.
