Suppress function output

Question

I have a short function which uses textscan to read data into a variable.

My problem is that I always get this:

>>function(\'funct         


        

Answer 1

The simplest way to avoid having output printed out is to not assign the first output argument if no output argument was requested:

function [aOut,b,c] = doSomething

%# create a,b,c normally
a = 1;
b = 4;
c = 3;

%# only assign aOut if any output is requested
if nargout > 0
   aOut = a;
end

Answer 2

You can suppress the output by remove output arguments (or return values) of the function. OR Try use Variable Number of Outputs, see Support Variable Number of Outputs

function varargout = foo
    nOutputs = nargout;
    varargout = cell(1,nOutputs);
    for k = 1:nOutputs;
        varargout{k} = k;
    end
end

You type >>foo and get nothing. You type >>a=foo and get >>a=1. You type >>[a,b]=foo and get >>a=1 >>b=2.

You can thus suppress output by NOT providing any output arguments.

Answer 3

You could try using the diary functionality. It redirects all input and output from the command prompt to a file of your choice. If you only turn it on during a specific function, no input should be captured. I admit it is a bit of a clumsy solution as the diary on/off state is global to matlab, but it might be ok in your case.
