How to convert ANSYS(Harwell-Boeing) stiffness matrix to MATLAB?

12 December 2018 0 7K Report

Hi,

I have tried to convert ANSYS(Harwell-Boeing) stiffness and mass-matrix to MATLAB-format. I obtain the matrices as sparse matrices in a txt file. I would like to covert them to ''full or normal'' size matrices. So that i can change boundary conditions and solve the eigenvalue problem in MATLAB.

I have tried a solution proposed on researchgate, where i use the link below, but i can not get it to work.

Hope some one can help me solve this problem.
