MATLAB Central Newsreader - catching \n (newline)

catching \n (newline)

Naor Movshovitz — Mon, 20 Aug 2007 22:33:06 -0400

sorry about the stupid question but,

>> a=sprintf('\n');
>> strcmp(a,'\n')

ans =

0

and i don't see anything in the help for strcmp.

Thanks,

In the *printf() I/O functions, \n is a special token sequence
representing newline. In most other places in matlab, \n is
a two character sequence, \ and n.

>> a=sprintf('\n');
>> strcmp(a,char(10))

ans =

     1
>> length('\n')

ans =

     2

replace with: strcmp(a,sprinf('\n'));

Note: this is a platform-independent solution, that takes
care of Unix (\n=char(10)), PCs (\n=[char(10),char(13)]) and
Macs (\n=char(13)). Don't use char(10),char(13) unless
you're certain about your intended platform. FYI, you can
get your system's line separator using the following:

double(char(java.lang.System.getProperty('line.separator')))
