Thread Subject: fprintf for standalone executable

I am trying to make a standalone executeable that prints
data to a text file.

I am able to compile and run the program just fine, but the
output is not as desired.

The relevant snippet of code in the mfile in the mfile is:

%write the data matrix
for k = 1:np
 fprintf(fid,'%-6.2f\t', data(k,:));
 fprintf(fid, '\n');
end

As an matlab function it functions properly.
Upon compilation with mcc and executing the program I get
a non-sensical output. (Example of 46 x 512 data matrix
output is shown below).

I know the compiler has limitations on the functions that
are properly executed with a standalone executable, for
instance 'input' does not work, nor does 'save' with tabs
and ascii options. Does fprintf also not work? Any ideas
why I am not getting the desired output and how to fix this?

Many thanks.

Example output...should be a 46 columns by 512 lines...and
it is nowhere close.
