Re: missing functions db2pow() and pow2db()

[siko1056]

Hello,

https://www.mathworks.com/help/signal/ref/db2pow.html
https://www.mathworks.com/help/signal/ref/pow2db.html

are as far as I see one-liners, you can distribute within your software,
until they are included into the signal package:

function y = db2pow(ydb)
  y = 10.^(ydb/10)
endfunction

function ydb = pow2db(y)
  ydb = 10*log10(y);
endfunction

I think the wiki page is up-to-date, currently they are not included
http://octave.sourceforge.net/signal/overview.html . Maybe Mike Miller has
time to add them? Or is it more difficult than I think?

HTH, Kai
