MATLAB Central - Loren on the Art of MATLAB » Creating Sparse Finite-Element Matrices in MATLAB MATLAB is Slow? Only If You Use It Incorrectly From time to time, I hear comments such as "MATLAB is slow for large finite-element problems." When I look at the details, the problem is typically due to an overuse of A(i,j)= ... when creating the sparse ma
Programing the Finite Element Method with Matlab 4 Finite Element Data Structures in Matlab Here we discuss the data structures used in the nite element method and speci cally those that are implemented in the example code. These are some-what arbitrary in that one can imagine numerous ways to store the
