How to check the output

I'm very new to Matlab. I have a code snippet (example) like this;

How to check the output of this function? Sorry for the fundmental question

function A = warmUpExercise()
%WARMUPEXERCISE Example function in octave
%   A = WARMUPEXERCISE() is an example function that returns the 5x5 identity matrix

A = [];
% ============= YOUR CODE HERE ==============
% Instructions: Return the 5x5 identity matrix 
%               In octave, we return values by defining which variables
%               represent the return values (at the top of the file)
%               and then set them accordingly. 



A = eye(5);
% ===========================================


end

you've defined the function to be:

function A = warmUpExercise()

so the output is going to be whatever A is defined to be in the function.

because your function takes 0 inputs, just run it on the matlab command line:

warmUpExercise

and you will see it output eye(5)
