## Bisection Method of Root Finding; Explained in Detail

Introduction The bisection method is one of the good computational methods (or numerical method) for finding the root of an equation or polynomial or function. This method is easy to learn and easy to implement in any programming language. But before going to the Bisection Method, let’s first understand the meaning of the root. Root …

## Fortran Do Loop | Tutorial 11

Introduction We use computational method to perform many calculations. That means we use programming language (or certain code) to solve almost all type of complex problems. Why this? One of the reasons behind this is: code can iterate over and over again according to our needs. I mean we can perform the same process so …

## Fortran program for dot product of three vectors or scalar triple product

Scalar Product of three vectors: Scalar Product or dot product of three vectors is also known as Scalar Triple product and is defined by: And = = To find scalar triple product, first we will find the cross product between two vectors and then do dot product of that result with remaining vector. Program to …

## Fortran Program for transpose of matrix and check whether it is symmetric or not

Symmetric Matrix : Any square matrix is said to be symmetric if its transpose is equal to its matrix itself. let A be the square matrix of 3X3 order and AT be its transpose matrix, then the condition for matrix to be symmetric is: AT = A If that condition is failed, then the matrix …

Fortran Problem Solving part 1 is already published. So go and check it out. This article covers some questions that can be solved using Fortran Programming Language and you need some knowledge before proceeding here. So, I suggest you read all the previous lessons covered in Fortran. Fortran Problem Solving: Question In order to solve …

## FORTRAN Select case statement | TUTORIAL 9

Select Case statement is another tool for logical decision in FORTRAN. We have used if statement to control decisions in FORTRAN in the previous lessons. But Select Case statement gives more control over the if statement. In the previous lessons, we used a logical operator with if statement to completer our task. The code became …

## FORTRAN Tutorial 8 | Logical Operator | Decision Control

Welcome to the new lesson of the FORTRAN programming tutorial. Before going in, I suggest you go through previous lessons of FORTRAN. We will focus on Logical Operators in this lesson. Logical Operator Logical Operators in FORTRAN helps to combine two or more expressions to a single one. The logical operators of FORTRAN programming language …

## FORTRAN Tutorial Lesson 7 | If … else if statement

Else if statement works in the same way as if else works. But only difference is, more expressions can be used in else if statement. Before you move on to this lesson, be sure to go through the previous lessons. Check out other lessons. Need of ELSE IF statement If you have learned through my …

## Fortran Tutorial Lesson 6 | Decision Control | If Else statement

Welcome to the tutorial of Decision Control in FORTRAN Programming Language. Before you start, I would suggest you to go through the previous lessons. Decision Control Like we humans control the decision, the program also has control over the decision with the help of code. Every high-level programming language has such a feature. FORTRAN program …

## FORTRAN Tutorial Lesson 5 | Problem Solving 1

Welcome to the first post for problem solving in FORTRAN. I strongly recommend watching my previous lessons. Check my FORTRAN programming page for more tutorials. If you are confident enough about the previous lessons, lets dive right to the problems. Question 1: To find the mid-point, we have formula: Lets see the steps written in …
