Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a large matrix from finite element analysis with only 12 non-zero values out of 100 elements. How would you convert this to a sparse matrix representation?

💡 Hint: Think about what it means to store only what's necessary.

Challenge 2 Hard

Analyze a scenario where using a dense matrix for a problem caused inefficiencies. How would sparse matrices solve these pitfalls?

💡 Hint: Consider the difference between filling a balloon and only keeping the essential air!
