I'm facing the problem to get compiled an old MEX wrapper function that should interface Matlab with some C code.
Such wrapper was done for Matlab 6 and works for Matlab 7 but now when I try to compile it with the Matlab 2008a I got some weird problems.
If I use the command:
mex ./src/myCfile.c -v -L ./bin
Matlab will complain with:

I have about a million observations that I want to save into a
dataset. Would the file be smaller if I saved it in Matlab or in
SAS? For approximately 20 columns, how big would it be? Thanks for
any help you can provide.
