The basic steps to getting this work are gone over below for a specific use case where I would like to use a MATLAB (*.m) file to compute a material model response for a user material. The basics steps are as follows. (1) Have MATLAB and the MATLAB Engine installed. (2) Create a user macro that will start the MATLAB engine. This permits..." current

There are two (short arrays) <code>hr( )</code> of type real*8 and <code>mr( )</code> of type integer, which are both defined in the common block <code>comblk.h</code>. When FEAP arrays are allocated they are done so using the system <code>malloc</code>.
