Fortran: Type/Rank mismatch error

    I can't seem to find any useful documentation for this.

    I am trying to pass a function through an integration function as an argument.

    integrate(my_func,parameters)

    But when I try this, I get a Type/rank mismatch error.

    The integrator has the following structure in at the top

    RECURSIVE function integrate(func,parameters) RESULT(inth)
    implicit none
    REAL(dbp) inth, func, parameters

    interface
    function func(xp,yp,zp) RESULT(vfun2d)

    My function has the following structure:

    function my_func(x,y,z) result(out)
    real(dbp) :: out
    real, intent(in) :: x,y,z

    Not sure what the problem is.

    Any help would be appreciated. Thanks
