DESCRIPTION

  Computes the present-day cold dark matter (CDM) power spectrum as a 
  function of a wavenumber.

ARGUMENTS

   znorm : Redshift normalization

   n : Spectral index

   omega0 : Present mass density

   h : Hubble constant

   lambda0 : Density parameter due to cosmological constant

   powerspectrum : The generated power spectrum
