Keeping this slow down due to the interpretive nature of Matlab in mind, one programming construct that should be avoided at all costs is the for loop, especially nested for loops since these can make a Matlab programs run time orders of magnitude longer than may be needed. Often for loops can be eliminated using Matlabs vectorized addressing.

The computer implementation is carried out using MATLAB, while the practical applications are carried out in both MATLAB and Abaqus.
