filesep for window '\', which may cause sprintf doesn't work for some '\%d' string, how can i avoid ?

str = " \num_%d " ;

result = sprintf(str, 1) ;

the above example can not output : " \num_1 " normally.

When I use the filesep global var of matlab in window, ' \ ' will come out, which cause the sprintf dosen't work.

How can I avoid the above situation without changing the function of sprintf ?

Hi Huang Chi-En,

please refer to sprintf-documentation; special characters might need different syntax. Since backslash is an escape character, you would have to use "\\" instead:

str = " \\num_%d ";
result = sprintf(str, 1);

Kind regards,

Robert
