  - unmix
```
double[][] unmix(double[][] spectra)
```
    Performs a linear spectral unmixing of a set of spectra.
    
    Parameters:
    
    spectra - the spectra, where number of rows = number of spectral channels number of cols = number of spectra
    
    Returns:
    
    the abundances, where number of rows = number of endmembers number of cols = number of spectra
  - mix
```
double[][] mix(double[][] abundances)
```
    Calculates the spectra for a set of abundances.
    
    Parameters:
    
    abundances - the abundances, where number of rows = number of endmembers number of cols = number of spectra
    
    Returns:
    
    the resulting spectra, where number of rows = number of spectral channels number of cols = number of spectra
