Problem with function in fortran 95
I am writing a function in fortran 95, but the intrinsic function MATMUL is not working properly. Here's an example.
SUBROUTINE mymult(x,y,res,m,n)
IMPLICIT NONE
INTEGER :: m,n
REAL :: x, y, res
DIMENSION :: x(m,n), y(n,m), res(m,m)
res = MATMUL(x,y)
END SUBROUTINE mymult
R CMD SHLIB mat.f95
In R:
dyn.load("mat.so")
x <- matrix(1:20,5)
l <- nrow(x)
c <- ncol(x)
y...
