## Introduction to online lu decomposition calculator with steps

The lu decomposition method calculator is an online tool that evaluates the matrix into lower triangular and upper triangular forms. It reduces the matrix into echelon form by applying different row or column operations. Lu factorization method calculator helps find the solution to a given system by making the expansion method easier.

In matrix algebra, you often have to use the echelon form method for different purposes. The LU factorization method converts the matrix into lower or upper triangular form. Here we introduce lu decomposition solver that can compute and find LU factorization of a given matrix.

## The formula used by matrix lu decomposition calculator with steps

The LU factorization refers to the factorization of a matrix into two factors, lower and upper triangular matrices with proper row or column orderings. Let A be a square matrix of order3-by-3 then,

$$ A = \begin{bmatrix} a & b & c \\ d & e & f \\ g & h & i \\ \end{bmatrix} $$

The LU decomposition of a matrix A can be written as:

$$ A \;=\; LU $$

Where,

$$ L = \begin{bmatrix} a & b & c \\ 0 & e & f \\ 0 & 0 & i \\ \end{bmatrix} $$

And

$$ L = \begin{bmatrix} a & 0 & 0 \\ d & e & 0 \\ g & h & i \\ \end{bmatrix} $$

L = Lower Triangular Matrix

U = Upper Triangular Matrix

The lu factorization calculator with steps uses the above formula for the LU factorization of a matrix and to find the lu decomposition. It reduces the matrix into the lower triangular matrix by making all entries zero below the diagonal elements, similarly to the upper triangular matrix.

## How to use lu factorization method calculator with steps?

It is easy to factorize a matrix into lower and upper triangular forms using the LU decomposition calculator, because it contains simple steps. These steps are:

- In the first step, you need to select the number of rows and columns from the respective options.
