str2num and commas

Hi. str2num doesn't seem to convert '20,000' to 20E3. Instead, it becomes a vector of 2 elements: 20 and 0. Is there a way around this or should I replace the comma in the string with '' before doing string2num? Thanks!

I think str2num considers '20' and '000' as two different strings because of the comma. What is the output that you are looking for? if you use str2double it returns 20000 . Hope that serves your purpose.

AH! Yes, I was looking for '20,000' to be converted to 20000.

OK then I think str2double will solve your problem.
