Given the matrix x, return the matrix y with non zero elements replaced with 1.
Example:
Input x = [ 1 2 0 0 0
0 0 5 0 0
2 7 0 0 0
0 6 9 3 3 ] Output y is [ 1 1 0 0 0
0 0 1 0 0
1 1 0 0 0
0 1 1 1 1 ]

>> isequal(NaN,NaN)
ans =
0
Therefore, the second test is inappropriate
isequaln should be used.
The way the problem is written, all nonzero elements, including NaN, should be changed to 1, but the test case doesn't work this way.
I updated the second test with isequaln so that NaN == NaN is true.
It should be mentioned that 1 must be placed in the non-zero elements except for NaN.
Replace all nonzero numbers with 1. Leave any NaN elements as NaN.
