Given the matrix x, return the sum of all elements of matrix.
Input x = [ 1 2 0 0 0
0 6 9 3 3 ]
Output y is 24.
Input x = [ 1 NaN 0 0 0
0 6 9 3 3 ]
Output y is NaN.
isequal(NaN, NaN) always return false. By definition Nans are not equal to each other. If you want test that a result is NaN, either use isnan, or use isequaln
The problem is unsolvable due to the second test.
I agree guys! something wrong
please use the function: isequalwithequalnans
Thanks for the suggestions. I fixed with isequalwithequalnans.
