Thanks for the patch, it's good, but - what makes you think matlab can
handle 64 characters of fieldname? The standard, here:
"Field Name Length Subelement
This subelement specifies the maximum length of a Field Name. MATLAB
sets this limit to 32 (31 characters and a NULL terminator). In a MAT-file
created by MATLAB, this subelement always uses the compressed data
I take this to mean the maximum field name length is 31 characters.
Have you got other information somewhere?
