Matlab R2009b returns '\a'regexprep ('a', '(\w)', "\\$1") Should it be '\a' or '$1'? In the first case, one would get the same result from using a replacement pattern of '\\$1' or "\\$1" which is odd because usually single quotes and double quotes are not interchangeable. On the other hand, Perl would return '\a' for the regexprep above. |
