Why does TEXTSCAN ignore my whitespace parameter in MATLAB 7.0.1 (R14SP1)?

When I try to read in a file of the following format:

 "5","10","20"

 "10","256","13"

using the following TEXTSCAN command:

A = textscan(fid,'%f%s%f','whitespace','\b\t" ','delimiter',',')

the contents of A{2} are:

     10"

     256"

It appears that my whitespace format specification is being ignored.

This enhancement has been incorporated in Release 2006b (R2006b). For previous product releases, read below for any possible workarounds:

There is an issue in MATLAB 7.0.1 (R14SP1) in the way that TEXTSCAN handles the %s format with a custom whitespace option. To work around this issue, you can clean the resulting data using the STRREP command. For example, you might use:

A{2} = strrep(A{2},'"','');
