Hi, I want to write data to text file using fprintf. I want to get the output like the the attachment (expected). However, I got an output with messy space (result). Is there a way to handle this matter? I would very appreciate it.

What is the output you are trying to write into textfile? A matrix?

You need to proceed like shown below.

A = rand(4) ;% Demo matrix
[mrows, ncols] = size(A) ;
fmt = [repmat('%f  ', 1, ncols) '\n'] ;
fprintf(fmt, A.')
