>> isequal(NaN,NaN)
ans =
0

Therefore, the second test is inappropriate

Jan Orwat on 6 Jun 2014

isequaln should be used.

Jon on 6 Jun 2014

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.

Ned Gulley on 6 Jun 2014

I updated the second test with isequaln so that NaN == NaN is true.

Stanislao Pinzón on 17 May 2020

It should be mentioned that 1 must be placed in the non-zero elements except for NaN.

Brianne Tengan on 12 Dec 2020

Replace all nonzero numbers with 1. Leave any NaN elements as NaN.
