Existing code:

n=3

reshape(randperm(n^2),n,n)

_____________________

This one line of code does exactly what I want. Depending on the value of n; a matrix of n size produces unique element values between 1-n^2.

I'd like to call this function something; randomMatrix(n), so that I can just change the 'n' to do everything above. I'm not sure if I'm asking this clearly, so I'll quote the question from my homework.

I'm told to 'write a function called randomMatrix(n)' that does exactly what my eisting code does, I essentially just need to call the function by that name.

note: I've tried something like

function A = randomMatrix(n)

A = reshape(randperm(n^2),n,n)

end.

I tried to follow this https://www.mathworks.com/help/matlab/ref/function.html

May someone help me out /annotate their code?

Your code looks fine except you do not add a period after the "end" keyword and you should put a semicolon after the reshape line to suppress MATLAB displaying the value of A to the command window. What is wrong?
