Test Suite

Test Status Code Input and Output
1   Fail
x = [3 2 1 3; 3 0 0 1; 0 4 3 1]; y = matrixManipulation(x); v = 3:15; assert(isequal(x(1,:),y(1,:))) assert(isempty(setdiff(y(2,:),v))) assert(isempty(setdiff(y(3,:),v)))

Unable to perform assignment because the size of the left side is 1-by-4 and the size of the right side is 4-by-4. Error in matrixManipulation (line 4) x(r,:) = randi(12, size(x,2)) + 3 Error in Test1 (line 2) y = matrixManipulation(x);

2   Fail
x = eye(4); y = matrixManipulation(x); v = 3:15; for i = 1:4 assert(isempty(setdiff(y(i,:),v))) end

Unable to perform assignment because the size of the left side is 1-by-4 and the size of the right side is 4-by-4. Error in matrixManipulation (line 4) x(r,:) = randi(12, size(x,2)) + 3 Error in Test2 (line 2) y = matrixManipulation(x);

3   Pass
x = ones(4); y = matrixManipulation(x); assert(isequal(x,y))

y = 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
