% CONVERT2INTERVAL converts the vector VALUES into a length of VALUES 
% times ( INTERVALS + 2 ) matrix. 
% The range from MIN (excluded) to MAX (included) is split into BINCOUNT
% many equivalent bins. Underflows (including exact values of MIN) are put 
% in the first bin (underflow bin), overflows in the last bin (overflow 
% bin).
% The first inputs are mandatory. Default for BINCOUNT and MIN are set by 
% FINDINTERVALBIN.
