fortran90/95 format, convenience called scientific computing, Newton-Raphson, can be used to find the linear/non-linear equation f (x) = 0 the numerical solution. The standard mathematical expressions represented by f (x) f is a function of the variable x, which typically forms the expression for f (x, a, b, ...) = 0, F is defined a function of more than one variable. In this case, the variables other than x is fixed and as a parameter, and the Newton-Raphson algorithm attempts to find a numerical solution for variable x.
