Improving sqrtm

[Mudit Sharma]

All,

I'm improving sqrtm in Octave and want to align it with

the sqrtm from Matlab which has 3 output arguments,

whereas the existing sqrtm.cc from octave has 2 .

Here's the link for sqrtm from Matlab:
https://github.com/RickOne16/sqrtm/blob/master/sqrtm.m

and this is octave's sqrtm:
https://github.com/RickOne16/sqrtm/blob/master/sqrtm.cc

How do I change the octave's sqrtm code to align it with that

from Matlab which has 3 output arguments?

Bests,

Mudit
