function ab=sr_plana(dig,nofdig,N)
%SR_PLANA  Recurrence coefficients for Plana weight functions.
%   AB=SR_PLANA(DIG,NOFDIG,N) generates in DIG-digit arithmetic
%   the first N recurrence coefficients for the weight function
%   w(x)=|x|/(exp(2*pi*|x|)-1) on [-Inf,Inf] and places them to 
%   NOFDIG digits into the Nx2 array AB.
