CMEX

[Todd Vernon]

Our site uses Matlab 3.0 and now is moving to 4.0. We have
a few CMEX programs we generated to load large files containing
time history data sets.

Due to the way Matlab handles CMEX interaction, ( all passed
back data must be in a left hand argument), this makes it
very difficult to load data sets with unknown number or
matrices.

Our data is mostly vector data, so what we do is pass back
2 left hand args, one that contains all our 1-by-n vectors
packed into one matrix, and the other a matrix of characters
that make up each vector name. After words, we have a m-file
that breaks apart each seperate vector putting it in a matlab
variable by the name in the other matix. What a PAIN.

Are we missing something here. We really need a way to create
matrices as we load the data and not have our hands tied by
having to pass them back through left hand args.

This really hinders our ability to access the data we need to
get to, any suggestions. Changing data format is NOT an option.

Thanks in advance.

In article <1993Jan25....@news.dfrf.nasa.gov> Todd Vernon,

The MEX-file facility in MATLAB 4.0 includes a new routine called
mexPutMatrix that allows you to plop a matrix directly back into
the MATLAB workspace.
