%SR_HRF Recurrence coefficients for the half-range Freud 
%weight function.
%   SR_HRF(DIG,NOFDIG,N,MU,NU) generates the first N 
%   recurrence coefficients in DIG-digit arithmetic for 
%   the weight function W(X)=X^MU*EXP(-X^NU) on [0,INF]
%   and places them to NOFDIG digits into the Nx2 array AB.
