MATLAB: Problem 44960 Rescale scores

doubt

The following code works fine with the first set of input tested however shows error for the second set. I am doing this on Cody. Could anyone tell me what's wrong?
function X = rescale_scores(X)
    A= 60:100;
    B= rescale(A,0,4);
    for c=1:40;
        for d=1:size(X,1);
        if X(d,length(X))==A(c);
    X(d,length(X))=B(c);
        end
        end
    end
    X
end

Best Answer

This can be solved using a one-liner
function X = rescale_scores(X)
    X(:,end) = interp1([60 100], [0 4], X(:,end));
end
