How do I solve this please? Write a function called 'corners' that takes a matrix as an input argument and returns four outputs

The elements at its corners in the order: 'top_left', 'top_right', 'bottom_left', 'bottom_right'. Without loops and if-statements.

An exact copy of how my code looks in the editor is below. My problem is I don't know how to test with random values in my command window. I don't know how it should be written. I'm a total beginner here though.

function [top_left, top_right, bottom_left, bottom_right]=corners(C)
top_left = C(1,1);
top_right = C(end,1);
bottom_left= C(1, end);
bottom_right = C(end,end);
end.

C = randi([2 10],4)  % give this as input in >> command window 

C = 4×4

5 2 5 5 8 8 6 7 9 8 2 3 3 5 4 6

[top_left, top_right, bottom_left, bottom_right] = corners(C)  % similarly this line 

top_left = 5

top_right = 3

bottom_left = 5

bottom_right = 6

function [top_left, top_right, bottom_left, bottom_right]=corners(C)  % save this program in script file same name % corners% 
top_left = C(1,1);
top_right = C(end,1);
bottom_left= C(1, end);
bottom_right = C(end,end);
end

save this program in script file same name corners and in same folder from where you call the function
