Should be

    x(u) = NaN;

without blips. What did the error message say?

[ricardo gunawan]

just incorect after i delete the blips its correct.

is there any difference in NaN and 'NaN'

i think is the same since its string

Yes they're different. NaN is a special object with special meaning. 'NaN' is a 3 byte character array that has no special meaning whatsoever. It just happens to have those characters in it but it has no relation to the real, special NaN object whatsoever.

@Image Analyst: To be nit-picking: 'NaN' is a 3 character array. But a char uses 2 bytes, such that 'NaN' has 6 bytes.
