- 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.
