[Matlab] Partition Matrix code

[Image: info.png]
partMatrix.m

This MATLAB function was developed for applications of the direct stiffness method for structural analysis which involves partitioning stiffness matrices and load/displacements vectors as well as reconstructing them based on the support conditions of each node of the structure.

The function was written using logical indexing to avoid looping, and as a result the process is much more efficient at partitioning matrices. While this function performs a relatively simple task, it will be useful to those who want to improve the performance of existing FEA code in MATLAB.

Source code below to avoid problems with dead links. Been a while since I used it but should be correct revision. Enjoy. Feedback appreciated
