Test Suite

Test Status Code Input and Output
1   Fail

Assertion failed.

2   Fail

Assertion failed.

3   Fail

Assertion failed.

Error using vertcat Dimensions of arrays being concatenated are not consistent. Error in matcat (line 2) x = vertcat(row_sums,col_sums); Error in Test4 (line 3) x = matcat(row_sums,col_sums);

5   Fail
