Hello,

Is someone able to explain to me what does the function "matscale" do?
There is no entry in the manual :(
It is a mex file in the Control Toolbox and is used, for instance, by "mscale".

Thank you very much for the help.

Best Regards,

-- Sergio

"scale the matrix using the projection radius", at least according to the
comments in http://programming.itags.org/matlab/43628/

I do not see any evidence that there is an "mscale" provided with any part of
Matlab. I do see "mdscale" in the the Stats toolbox.

I do see that matscale.glx* is included in the Linux RPM for the control
toolbox for at least one version. I would venture that it is an undocumented
internal utility function that was introduced in some version and may already
be removed from current versions.
