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 MATLABmmwrite.m for writing the matrix into a Matrix Market file

In Ansys...

*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 = mmread('mytemp.mtx'); % mmread.m must is in working directory
