MATLAB: Printing function results to the Workspace

Question

So I have a simple function

function range(x,y)

%Finds the range between x and y

y-x

When I run the function, I would like the result to output to the workspace. If I run:

range(4,5)

ans =

     1

So i want the Workspace to then show "Range" with Value = 1

My first thought was to type

range_a = range(4,5)

but it responds with:

??? Error using ==> range Too many output arguments.

Any ideas would be greatly appreciated!

Answer 1

You get that error because you haven't given the function any output arguments. So let's give it one!

function R = range(x,y)
%Finds the range between x and y
R = y-x;

Now from the command line:

range(4,5)

Or,

RNG = range(4,5)

Also, you would probably find it worthwhile to read the function doc:
