This change has been incorporated into the documentation in Release 2009b (R2009b). For previous releases, read below for any additional information:

This is an expected behavior in MATLAB. The character '\' is a MATLAB operator and is hence interpreted. In order to pass in the '\' character in its un-interpreted form to the TEXTSCAN command, it needs to be preceeded by the escape character '\'. Therefore, to use '\' as the delimiter in the TEXTSCAN command, execute:

textscan(p,'%s','delimiter','\\');
