%
% There are three formats used to represent wavelength
% sampling in the Psychtoolbox.
% S-format - a 3 by 1 row vector [start step numberSamples].
% wls-format - a list of evenly spaced wavelengths.
% struct-format - a structure with fields start, step, and numberSamples.
%
% The S-format predates the availability of structures in MATLAB, but
% is used widely in extant code. Low level conversion routines transform
% between these representations, and in particular routines MakeItS,
% MakeItWls, and MakeItStruct take any of the three formats and return
% one. By calling one of these before using wavelength format information,
% it is possible to write code that is compatible with all three.
