This problem needs improvement.
FIRST: the Problem Statement is badly flawed. The starting matrix which is presented appears to contain zero for all entries in the first two rows, although apparently this is not what was intended (according to the Test Suite). SECOND: the Test Suite explicitly contains the solution, and there is only one test case. Asking people not to look is futile. Test Suites should be constructed with multiple cases by generalising the Problem Statement (e.g. allowing different numbers of rows in the starting matrix). See Problem 44616 for further discussion. —DIV

In addition to what David has mentioned, use tolerance based methods while dealing with floats instead of using isequal, which is just lazy.
