%SR_LOGRATSQ Recurrence coefficients for polynomials orthogonal
%with respect to a logarithmic weight function with rational
%square-root argument.
%   AB=SR_LOGRATSQ(DIG,NOFDIG,N) generates in DIG-digit arithmetic
%   the first N recurrence coefficients for the weight function 
%   w(x)=log((1+x^(1/2))/(1-x^(1/2))) on [0,1] and places them to 
%   NOFDIG digits into the Nx2 array AB.
