Re: input with line break

[Santiago Higuera]

Thanks, Przemek.  I didn't know.

I read in 'Free your numbers'

5.1 Escape Sequences in String Constants
In double-quoted strings, the backslash character is used to introduce 
escape sequences that
represent other characters. For example, ‘\n’ embeds a newline character 
in a double-quoted
string and ‘\"’ embeds a double quote character. In single-quoted 
strings, backslash is not
a special character.

I read in 'help fprintf':

Implementation Note: For compatibility with MATLAB, escape
     sequences in the template string (e.g., "\n" => newline) are
     expanded even when the template string is defined with single
     quotes.

It's a little confused for me, I don't understand why  single and double 
quoted string are different. I don't understand what is the objective or 
the advantage of this difference.
