Standardizes new spectra using transform from STDGEN.
- stdspec = stdize(nspec,stdmat,stdvect)
Inputs are the new spectra to be standardized nspec, and the standardization matrix stdmat (output from stdgen).
Optional input stdvect is the offset vector (output from stdgen). Note that if stdvect was calculated when generating the transform with STDGEN, then it should be input when applying the transform with STDIZE.
The output is a matrix of the standardized spectra stdspec.
