Just as F format with specific precision or including the graphics/typesetting?
The former is simple (well as simple as anything ever gets with the stupid C-language formatting string that doesn't allow for repeat counts, anyway)...
fmt=[repmat('%10.6f',1,size(TX,2)-1) '%10.6f\n'];
fprintf(fid,fmt,TX.')
Have to fopen the file to have valid file handle, FID, first, of course, the fclose and NB: the transpose operator to output values by row; internal ML storage is column-major so would show up as the transpose in output if don't.
