function ab=sr_powexp_cheb(dig,nofdig,N,nu,c)
%SR_POWEXP_CHEB Recurrence coefficients for a subrange
%exponential integral weight function E_nu(x) on [0,c].
%   AB=SR_POWEXP_CHEB(DIG,NOFDIG,N,NU,C) generates in  
%   DIG-digit arithmetic the first N recurrence coefficients 
%   for the weight function W(X)=E_NU(X) on [0,C], NU>0, C>0,
%   using the classical Chebyshev algorithm. The results
%   are placed to NOFDIG digits into the Nx2 array AB.
