Why does the HELP function not return any matches for many Fixed-Point Toolbox functions?

I type the following at the MATLAB command prompt to access the documentation for ISROW and ISCOLUMN:

help isrow

help iscolumn

But MATLAB indicates that these functions are not found.

This bug has been fixed in Release 2007a (R2007a). For previous product releases, read below for any possible workarounds:

There is a bug in MATLAB 7.2 (R2006a) and prior versions where the help for many Fixed-Point Toolbox functions, including ISROW and ISCOLUMN, cannot be accessed using the HELP function.

To work around this issue, use the DOC function to access the documentation for these functions, as in the following syntax:

doc isrow

doc iscolumn
