Test Suite

Test Status Code Input and Output
1   Fail
assert(isempty(maxdiag([])))

Unable to perform assignment because the indices on the left side are not compatible with the size of the right side. Error in maxdiag (line 6) y(k) = max(diag(x,i)); Error in Test1 (line 1) assert(isempty(maxdiag([])))

2   Fail
x = randi(100); assert(isequal(maxdiag(x),x))

Unable to perform assignment because the indices on the left side are not compatible with the size of the right side. Error in maxdiag (line 6) y(k) = max(diag(x,i)); Error in Test2 (line 2) assert(isequal(maxdiag(x),x))

3   Fail
x = randi(100,100,1); assert(isequal(maxdiag(x),x(end:-1:1)'))

Unable to perform assignment because the indices on the left side are not compatible with the size of the right side. Error in maxdiag (line 6) y(k) = max(diag(x,i)); Error in Test3 (line 2) assert(isequal(maxdiag(x),x(end:-1:1)'))

4   Fail
x = randi(100,1,100); assert(isequal(maxdiag(x),x))
