MATLAB: How suppress output from a user defined function

displayfunctionoutput

function [x,y] = myfn(a,b,c)

I intend to use the values of x and y for consequent operations.However the values of x and y are in matrix with big dimensions.As a result the command window is full of continuously changing values.I need to get rid of that.

Any way to suppress the display of x and y in command window but still use the values ?

I don't understand why the values are being displayed in the first place. As long as everything ends with a semicolon, there should be no display. Is there something in the function that explicitly displays something? If so, why?

MATLAB: Access outputs of functions with multiple outputs

There is a way to do it, but I am reluctant to share it because I don't think it is worthwhile to program this way. I cannot think of any reason one would want to do this, except to see if it could be done. Since I am that kind of curious person, I will show how to do it, but again I think you should go another route!

>> f = @(x,y,r) evalin('caller',[sprintf('[~,x]=twout(%.15f,%.15f);',x,y),r,'=x;'])
>> f(2,3,'r')  % Third arg is a string: [~,r] = twout(2,3)
>> r
r =
      -1

Simplest solution: set a default output value:

function [a,b] = myfn(x,y)
a = 1;
b = [];
if(x=y)
  b = 2;
end
end
