gauss laguerre – laguerre gauss modes
· LAGUERRE_RULE is a FORTRAN90 program which generates a specific Gauss-Laguerre quadrature rule, supportd on abraser input,, The rule is written to three files for easy use as input to other programs, The Gauss-Laguerre quadrature rule is used as follows: Integral a <= x < +oo exp – b * x …

I have two function in double integral from 0 to corromputy and I already use Gauss-Laguerre to solve one of them , But Now I have double integral in the form int int FM dM * Fp,M dP I want to repeat Gauss lageuerre or recall it to solve the integral that remains after the first integral over p then it remains a function over M multiplied by FM, How can I do that,
