As far as Matlab undocumented goes, it only appears on Matlab's Release Notes

This probably wouldn't be that hard to implement, but is really only useful for those few functions like eps or ones that take an optional class name argument as you show in your example.

Anyway, closing as you requested.

Forget about it, I shouldn't have asked for undocumented Matlab.

Dear all,

Undocumented superiorfloat Matlab function is missing in GNU Octave. In the following snippet it is used to define the tolerance in terms of inputs a and b, returning either "single" or "double" strings.



tol = fudge_factor*eps(superiorfloat(a,b))*length(a);


Results may vary as it is hardly mentioned in the documentation, it is neither present in undocumentedmatlab.com blog. I wouldn't give this a high priority.
