Matrix Transfer between MATLAB and Ansys

Matrix Transfer * Reading and writing matrix or arrays to MATLAB and back can be painstaking as described by SimuTech in a well written article  using *TREAD  or *VREAD . Wouldn't it be great to have someone else do the heavy lifting for you on formatting etc? Fortunately there is a Matrix Market format sponsored by NIST that is also supported by Ansys and Matlab. There are two very useful MATLAB functions created just for this purpose: mmread.m   for reading in the Market Matrix file into MATLAB mmwrite.m for writing the matrix into a Matrix Market file Writing Matrix or Arrays from Ansys to be Read by MATLAB In Ansys... /prep7 *dim , c,, 10,10, 1 ! Example Matrix enow = 0 *do , ct, 1, 10              *do , ct2, 1, 10         c(ct,ct2) = ct*ct2     *enddo     *enddo     !!! Writes out Matrix to matlab *dmat , exportmatrix, D, import, APDL, c ! export to matrix file *export , exportmatrix, mmf, mytemp.mtx In MATLAB, the command is simply... c = mmrea
