strtok return nothing

Hi, all,

I have a question about strtok.

Run [T,D]=strtok(num2str(5.5),'0.5') return T='' D=''

what's wrong? other number works fine.

There's no 0.5 delimiter on the string, strtok should return T=5.5 but it doesn't, that's weird because it says on the documentation: If no delimiters are found in the body of the input string, then the entire string (excluding any leading delimiting characters) is returned in token, and remain is an empty string ('')

Like this [T,D]=strtok(num2str(5.5),0.5) it works like it says on the documentation.

[T,D]=strtok(num2str(5.5),'.5') return T='' D='' have the same problem.
