Write a function called pitty that takes a matrix called ab as an input argument. The matrix ab has exactly two columns. The function should return a column vector c that contains positive values each of which satisfies the Pythagorean Theorem, a2 + b2 = c2, for the corresponding row of ab assuming that the two elements on each row of ab correspond to one pair, a and b, respectively, in the theorem. Note that the built-in MATLAB function sqrt computes the square root and you are allowed to use it.

function c = pitty(ab)
%Input matrix ab has exactly two columns
%Output column vector c contains positive values satisfies a2 + b2 = c2
%Example:
%    ab = [3 4;1 2]
%    c = pitty(ab)
c = sqrt(ab(:,1).^2 + ab(:,2).^2);%Pythagorean theorem formula
