 # What Is Direct Method And Iterative Method?

## Which is iterative method?

In computational mathematics, an iterative method is a mathematical procedure that uses an initial value to generate a sequence of improving approximate solutions for a class of problems, in which the n-th approximation is derived from the previous ones..

## Which method is direct method?

Direct methods provide the exact solution of an equation system in a finite number of steps and try to solve the problem immediately. When this method is used for finite arithmetic calculations usually obtains an approximate solution, generally due to rounding errors.

## Which method is direct method for solving simultaneous equations?

Which of the methods is direct method for solving simultaneous algebraic equations? Explanation: Cramer’s rule is the direct method for solving simultaneous algebraic equations.

## What are direct methods for solving linear systems?

By the term direct methods we mean methods that theoretically give the exact solution to the system in a finite number of steps such as the Gaussian elimination. In practice, of course, the solution obtained will be contaminated by the round-off error that is involved with the arithmetic being used.

## What means iterative?

: involving repetition: such as. a : expressing repetition of a verbal action. b : utilizing the repetition of a sequence of operations or procedures iterative programming methods.

## What does iterative process mean?

The iterative process is simply a series of steps that you repeat, tweaking and improving your product with each cycle. In practical terms, think of it as practice to make your product perfect.
