[Matlab] Partition Matrix code - elbarto_87 - 11-23-2009 [Matlab] Partition Matrix code
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.
