function ab=sr_sqgbinet(dig,nofdig,N,a)
%SR_SQGBINET  Recurrence coefficients for the squared generalized 
%Binet weight function.
%   AB=SR_SQGBINET(DIG,NOFDIG,N,A) generates in DIG-digit arithmetic
%   the first N recurrence coefficients for orthogonal polynomials   
%   relative to the weight function w(x)=[log(1-A*exp(-|x|))]^2 on
%   [-Inf,Inf] using a moment-based method. The recurrence
%   coefficients to NOFDIG digits are placed into the Nx2 array AB.
