Function: gaindb

GAINDB  Increase/decrease level of signal
  Usage:  outsig = gaindb(insig,gn);

  GAINDB(insig,gn) increases the energy level of the signal by gn*
  dB.

  If gn is a scalar, the whole input signal is scaled.

  If gn is a vector, each column is scaled by the entries in
  gn. The length of gn must match the number of columns.

  GAINDB(insig,gn,dim) scales the signal along dimension dim.
