MATLAB: Delimiter must be a string (textscan R2010b)

Question

The following code works on R2013a

str = textscan('is it a version issue, or it is not.','%s','Delimiter',{' ',',','.'});

but it does not on R2010b, where I receive the following error:

Delimiter must be a string.

Any solution to this? Can you confirm it is a version issue?

Answer 1

What about:

str = textscan('is it a version issue, or it is not.', '%s', 'Delimiter', ' ,.');
