## M_PToP

##### >Psychtoolbox>PsychColorimetric

[M] = M_PToP(Psource,Pdest,T)

[M,dest] = M_PToP(Psource,Pdest,T,source)

Compute the conversion matrix between two color

spaces with known primaries.

The transformation requires a set of color matching

functions to describe the observer.

M - the conversion matrix

(n_chromacy by n_chromacy)

Psource - source color primary spectral power distributions

(n_wavelengths by n_chromacy)

Pdest - destination primary spectral power distributions

(n_wavelengths by n_chromacy)

T - a set of color matching functions

(n_chromacy by n_wavelengths)

### OPTIONAL

source - source tristimulus vectors

(n_chromacy by n_lights)

dest - destination tristimulus vectors

(n_chromacy by n_lights)

8/2/94 dhb Fixed bug in optional arg handling.
