How to define complicated function

[Anonymous47]

I have one function to define like that

f(x)=a(x)*b(x)*c(x)*d(x)

which a,b,c,d are independent ones.

For C language

to load the function within another function

it's better to include the definition within the form

just like

long f(x)

integer x;

long a(int);

long b(int);

long c(int);

longt d(int);

.....

i am not quite clear how it can be finished in Fortran.

Would any one tell me in detail?

There are several ways to declare this. The following is but one

Code:

function f(x)
    ! function return type declaration
    integer f:
    ! calling arg declartion
    integer :: x
    ! external function type declarations
    integer :: a,b,c,d
    ! code
    f=a(x)*b(x)*c(x)*d(x)
end function f
