How to not get an ans from function?

Hi,

I have created a function and it works the way I want it to. However, when I run the function I keep getting an 'ans' and I am not exactly sure why.

In the command window it looks like this:

The following vectors fulfill the demands above:
 
u2=[0,-1,1]
u3=[0,1,-1]
 

ans =

         0   -1    1

There are at least two possibilities.

(1) You have omitted a closing semicolon (;) somewhere in the function.

(2) You called the function without an output argument, and did not put a closing semicolon on the function call.

Without seeing your function and your call to it, I cannot speculate as to other reasons.

Ok, I see. But my function does have an output argument as well as closing semicolon.

function [u2, u3] = Exercise(W);

Your call to ‘Exercise’ (in your script) apparently does not have a closing semicolon. The function declaration itself does not need a closing semicolon.

For example:

This is correct:

function [u2, u3] = Exercise(W)

and this will not print ‘ans’ to your Command Window because it has an output assignment and a closing semicolon:

W = ...;
[u2, u3] = Exercise(W);

You can then use ‘u2’ and ‘u3’ afterwards in your script.
