HI there, so i am stuck again on trying to get a line of code in order to remove the 3rd column from any sized array in matlab by using a function. My current code is as follows. I looked up how to remove columns and I can do it but when using a function it gets messed up and doesnt work. It should only be one line of code to the right of the 'Z =' portion. I have included the quesstion as well in the image attatched. I have tried Z(:,3) = [] and it doesnt work. I also tried Z(A(:,3)) = [] and it aslo didnt work so now I am quite lost. Thank you!!
function Z = remove3(A)
Z = A(:,3);
end

Hint:
m = magic(4)
m(:,3) = []

The grader I have says that is incorrect for this particular problem. I gave this code a try earlier and had no luck. I think it only wants code on the right side of the 'Z =' or in your case the 'm = '.But thank you for the answer either way.
