But how can I put that xl=xl and use it on the equation again in program? Just give me one example and i'll do it for the rest of the. Program to demonstrate Secant method Program to demonstrate the Aitken. Index and description of example Fortran. It seems that the initial values for xold and xolder are too far from the solution.įortran Program For Secant Method Iteration.
Fortran program for secant method examples update#
If I figure this out I will update it to working.
Fortran program for secant method examples code#
EDIT: I have updated the code with some suggestions from users, still seeing quick divergence. I've done this on paper and understand the mechanics of the equations. I am trying to write a program to solve for pipe diameter for a pump system I've designed. Click on the program name to display the source code, which can be downloaded. List of Fortran90 Codes Numerical Mathematics and Computing Sixfth Edition Ward Cheney & David Kincaid Sample Fortran90 Codes In the following table, each line/entry contains the program file name and a brief description. Numerical Mathematics and Computing, 6th Ed. The method is based on The Intermediate Value Theorem which states that if f(x) is a continuous function and there are two real numbers a and b such that f(a)*f(b) 0 and f(b) < 0), then it is guaranteed that it has at least one root between them.Fortran Program For Secant Method Example Rating: 6,5/10 9557votes This method is used to find root of an equation in a given interval that is value of ‘x’ for which f(x) = 0. The method is also called the interval halving method, the binary search method or the dichotomy method. Transcendental function are non algebraic functions, for example f(x) = sin(x)*x – 3 or f(x) = e x + x 2 or f(x) = ln(x) + x …. + e where aa 1, a 2, … are constants and x is a variable. What are Algebraic and Transcendental functions?Īlgebraic function are the one which can be represented in the form of polynomials like f(x) = a 1x 3 + a 2x 2 + …. Input: A function of x, for example x 3 - x 2 + 2.Īnd two values: a = -200 and b = 300 such that Find root of function in interval (Or find a value of x such that f(x) is 0). Here f(x) represents algebraic or transcendental equation. Given a function f(x) on floating number x and two numbers ‘a’ and ‘b’ such that f(a)*f(b) < 0 and f(x) is continuous in.
