Implementing missing toolbox/package functions

[Svante Signell]

Hi,

I am writing some code for communications applications for research
purposes and found that e.g. root-raised-cosine functions (rcosine,
rcosfir, rcosiir, etc) are missing from the octave-communications
package. Are there code rules and template code available somewhere, in
case I want to contribute by writing some of the missing functions (to
start with as .m functions).

BTW: I found a list of missing package functions at:
http://www.denney.ws/octave/3.0.1/Communications.html
Is there an updated list somewhere?
