How to suppress command output?
显示 更早的评论
Matlab version - 7.1.2.0 (R2011a)
Hear me out here, I know that to suppress output you put a semicolon at the end of a line. However even after adding the semicolon at the end of each line of my .m file Matlab is still displaying an output of the actual line itself.
Ex: If my code was:
disp('x');
my output would be:
disp('x');
x
anybody know what might be causing this?
EDIT: Alright to clarify here if I wanted to display 'x' and I used the disp command not only does 'x' print out to the console but 'disp('x');' prints to the console as well, what I don't want to see is the disp part that prints out, any ideas?

I bet you have somehow turned "echo" on. Try putting in this line:
echo off;

That is automatically put into the "mfilename" variable, which is in scope everywhere. Put a line in that says:
fprintf('The name of this m-file is %s\n', mfilename);

The semicolon suppresses the output of the the replied value of a command or an assignment. If you call a function, which writes to the command window, appending the semicolon does not suppress this.
Examples:
fprintf('hello\n')
fprintf('hello\n');
numOfChars = fprintf('hello\n')
numOfChars = fprintf('hello\n');

How are you invoking your function? I do not see any
testing
in your command window, which suggests to me that perhaps you selected something from the GUI or used one of the shortcut keys; in that case the disp() could be arising from that.
