Today, we're starting our journey into the history of MATLAB. It was primarily developed by Cleve Moler in the 1970s. Can anyone tell me why MATLAB was created?
Was it to perform matrix computations?
Exactly! It aimed to provide an interactive tool to access advanced linear algebra routines. Now, can someone tell me which libraries it was derived from?
I think it's LINPACK and EISPACK?
Great! LINPACK and EISPACK are crucial for handling linear systems and eigenvalues. Remember, LINPACK is for linear algebra, and EISPACK is for eigenvalue problemsβlet's memorize that as 'LE' for Linear and Eigenvalue.
How did it gain popularity?
It gained popularity primarily through word of mouth since it wasn't officially distributed. Knowing this can help you recall how important community and user feedback was back then.
Key Contributions and Evolution

In addition to Cleve Moler, three other men played significant roles in the origins of MATLAB: J.H. Wilkinson, George Forsythe, and John Todd. Can anyone tell me why these figures are important?
They helped develop the foundational ideas and functionalities of MATLAB, right?
Exactly! They contributed to early developments in numerical methods. But there's more! In the 1980s, MATLAB was rewritten in C. What do you think this change contributed to its functionality?
Did it make MATLAB faster or add new plotting routines?
Right! Rewriting it in C enhanced performance and introduced plotting capabilities. Always remember 'C' stood for 'Celerity and Charting!'

Now, let's discuss MATLAB's legacy and how it has influenced other software. What other packages can you name that evolved from or parallel to MATLAB?
There's LAPACK and GNU Octave?
Absolutely! LAPACK, which stands for Linear Algebra Package, was developed as a successor to LINPACK and EISPACK. Knowing these connections can help us understand how tools evolve in computing.
What about the competition it faces?
Good point! Mathematica is one of its main competitors but focuses more on symbolic computation. So, you could say MATLAB is 'NUMERIC'βNurturing Usable Math and Routines In Code.

Quick Overview
Standard
MATLAB was primarily developed by Cleve Moler in the 1970s as an interactive tool to access linear algebra routines from FORTRAN libraries. Gaining popularity through word of mouth, it was rewritten in C in the 1980s to enhance its functionality, leading to the creation of The MathWorks to market it further. Notably, key figures like J.H. Wilkinson contributed to its creation, and it evolved alongside the emergence of other packages like LAPACK.
Detailed
Detailed Summary of the History of MATLAB
MATLAB (Matrix Laboratory) was developed by Cleve Moler in the 1970s, aiming to provide an interactive interface to access the pre-existing FORTRAN subroutines LINPACK and EISPACK, which are used for numerical linear algebra and eigenvalue problems. Initially, the tool gained traction through word of mouth due to its unofficial distribution.
In the 1980s, MATLAB underwent substantial rewriting in the C programming language, leading to an expansion of its functionalities, particularly in terms of plotting, which significantly enhanced its usability in mathematical computations. This period marked the foundation of The MathWorks, Inc. in 1984, which was established to focus on the marketing and further development of MATLAB.
Key contributors to MATLABβs early development also include J. H. Wilkinson, George Forsythe, and John Todd. It's essential to acknowledge the authors of LINPACK: Jack Dongara, Pete Steward, Jim Bunch, and Cleve Moler himself. Over time, a new linear algebra package, LAPACK, emerged as a successor to LINPACK and EISPACK, showcasing the evolving nature of computational tools in the field of numerical analysis.

Chapter Content
Developed primarily by Cleve Moler in the 1970βs.
Detailed Explanation
MATLAB was primarily developed by a mathematician named Cleve Moler during the 1970s. This initial development laid the groundwork for what would become a powerful tool in numerical computing and simulation. Cleve Moler aimed to create an interactive environment that would make it easier for users to perform mathematical calculations.
Examples & Analogies
Think of Cleve Moler as a chef in a kitchen trying to create a new dish. He experimented with different ingredients (mathematical concepts) to develop a unique recipe (MATLAB) that would be more accessible for people who want to cook (perform calculations).
Origins from LINPACK and EISPACK

Chapter Content
Derived from FORTRAN subroutines LINPACK and EISPACK, linear and eigenvalue systems.
Detailed Explanation
MATLAB was built on foundational subroutines that were originally written in the FORTRAN programming language. These subroutines, LINPACK and EISPACK, were designed to solve linear algebra problems and eigenvalue computations. By leveraging these powerful tools, MATLAB could provide efficient solutions for complex mathematical tasks.
Examples & Analogies
Imagine building a modern smartphone using technology and concepts from older devices. Just like MATLAB used established methods (LINPACK and EISPACK) to solve mathematical problems, the smartphone benefits from previous innovations in telecommunications and computing.
