I am sudhir currently pursuing btech in Electrical Engineering from IIT Bombay(India) and I am doing programming in C++ from the last 2 years.There is the list of function which are yet not implemented in signal package of octave. Can I take it as GSoC project.
Yes,certainly you can take part.
You should go through this wiki.octave.org/Summer_of_Code_Project_Ideas
and this https://wiki.octave.org/GNU_Octave_Wiki You can also implement those missing functions.
