Function Output?

Hello Experts,

Consider I have

function res = test(c)

      if c>0

          res=1;
      else
          break;
      end
end

I want function test to print nothing if c<0. How can I do it?

Thanks a lot!

Do you want something like this:

function res = test(c)
      if c>=0         
      res=1;
      else
         error('Input must be nonnegative');
      end
end

If you just want res to be empty, you can do:

function res = test(c)
      if c>0          
      res=1;
      else
       res = [];         
      end
end
