Hello,
I made a library for reading/writing MATLAB Mat-files in LabVIEW, and posted it on Sourceforge. It's written in pure G, with no external DLLs. Anyone is welcome to use the code if they want. It can be downloaded at http://matio-labview.sourceforge.net/. If you do try it out, I would appreciate any feedback you could provide.
Here is some sample code. I'm writing a cluster of various items to the file test.mat. This will create a structure in MATLAB with field names derived from the labels of the items in the cluster.
After running "load test.mat" in MATLAB, here is the result (shown in the variable editor):
Thanks,
Jim
