Re: GSOC 2017 Idea Improve logm, sqrtm, funm

[Michael D Godfrey]

You could start by looking at bug report:#44310. This is quite old, but has not
been worked on. Now that C++11 is in use the entire set of elementary functions
should be redone to make use of the math library. The current functions use
numerically unstable transformations.  As far as I remember only atanh was
corrected to use libm.

Doing this would be an important contribution and is not dependent on much
detailed knowledge of Octave.  Of course, carefully coded tests for each function
will be required and these will need to be included in the source code as is
done for other functions.

Thanks very much for offering to help.

Hello everyone,

As I introduced my self earlier, I'm a final year student majoring Electronincs & Instrumentation from BITS Pilani, India. I have strong coding skills and proficient in Matlab and C++.

I am looking forward to take part in GSOC 2017, and I'm interested to work on idea- improve logm, sqrtm, funm

I have been looking into the code base and found that it is well structured that help me a lot in becoming comfortable with the code base.

I will start contributing to GNU-Octave soon, but it will be excellent if anyone can point out some issue just for start. Some pointers will be really helpful to start working on this module.
Lastly I apologize if I have been rude in any manner.
