*DECK DQMOMO SUBROUTINE DQMOMO (ALFA, BETA, RI, RJ, RG, RH, INTEGR) C***BEGIN PROLOGUE DQMOMO C***PURPOSE This routine computes modified Chebyshev moments. The K-th C modified Chebyshev moment is defined as the integral over C (-1,1) of W(X)*T(K,X), where T(K,X) is the Chebyshev C polynomial of degree K.
