Hi,
I have "old" codes that call Fortran numerical_libraries routine GQRUL and DGQRUL for calculating Gauss-Legendre quadrature rule to perform numerical integration. I used to be able to just put a line in the main routine "USE numerical_libraries" and subsequently was able to call GQRUL and DGQRUL functions.
Currently, I have Intel® Parallel Studio XE Composer Edition for Fortran with Rogue Wave IMSL 7.0 for Windows*.
I have been trying to compile the old codes with routines from Numerical_libraries but I get the feeling that MKL that I have doesn't have GQRUL routine or in fact any kind of extensive array of routines for numerical integration that were in numerical_library.
Am I correct? I really need to use Gauss-Legendre quadrature rule routine; how do I go about this?
Thanks,
Byung
