calculate the rectified value

Hey, im new here. Today we were given the task of calculating the rectified value of a function. I have already written this function and it works as required. Now we have to compare this result with the build-in function of Matlab, but I can't find this function anywhere. Can someone please help me?

function [rectified_value] = my_rv(A)

%rectified value

%calculate rectified value of a series of data

% Input...matrix [] or function

a = size(A); %identify matrix dimension

amount_A = abs(A); %convert negative numbers to positive numbers

sum_a = sum(amount_A, "all"); %sum every single value in the matrix

numBer = a(1,1)*a(1,2); %calculate number of places within a matrix

rectified_value = (1./numBer).*(sum_a); %calculate the rectified value

end

built_in_value = mean(abs(A(:)))

Thank you very much, I didn't know it was that easy. Have a nice Sunday
