    Fortran Implementing Generalized Laguerre Polynomials in Fortran

    Hi! Im trying to do some rather easy QM-calculations in Fortran. To do that i need a routine that calculates the generalized Laguerre polynomials. I just did the simplest implementation of the equation: L^l_n(x)=\sum_{k=0}^n\frac{(n+l)!(-x^2)^k}{(n-k)!k!} I implemented this in the...

    Fortran What is the most optimized way to transpose a matrix in Fortran?

    Hi! I'm working on a programming project(fortran 77). and I need to transpose a big matrix, and for the moment I'm doing it by to do-loops: DO 20 J = 2,NP DO 10 I = 1,J-1 T = P(I,J) P(I,J) = P(J,I) P(J,I) = T 10 CONTINUE 20...
