Hi,

I tried writing a matrix to a text file using dlmwrite function, but it came out messed up.. no spaces and it looked terrible. How do I make it look spaced out properly between two columns and nicely aligned? I can't use xlswrite as the matrix has 2 million rows

Thanks!

Ok. This is what I meant. (attached screen shot) Any idea? :(

Either dlmwrite with a 'precision' that has a leading count like the %20 that I showed (in which case each column will be the same size), or else fopen/fprintf/fclose using a format specifier that is appropriate for each column.
