## Introduction to Matrix Calculator:

Matrix Calculator is an online tool that helps you to find the basic arithmetic operations that are performed on the given matrix. It is used to evaluate the **different order of matrices** like 2 by 2 matrices, 3 by 3 matrices, or any order only if they both have the same order.

The matrix solver is an essential tool for anyone whether he is a beginner or professional who wants to learn matrices in linear algebra. It escapes you from tedious or complex calculations of matrices and provides you with quick results for your problems.

## What is a Matrix?

A matrix is an **array of numbers**, symbols, or expressions, that are arranged in rows and columns in a rectangle shape.

Each element of a matrix denotes its row and column number. Matrices are a fundamental process in mathematics because it is used in a wide range of applications across science, engineering, and other fields.

## Representation of Matrix:

The Matrix Calculator **presents the matrix** in its mathematical form. Mathematically it can be written as:

$$ A \;=\; \left[ \begin{matrix} a_{11} & a_{12} & \cdots & a_{1n} \\ a_{21} & a_{22} & \cdots & a_{2n} \\ \vdots & \vdots & \ddots & \vdots \\ a_{m1} & a_{m2} & \cdots & a_{mn} \\ \end{matrix} \right] $$

Here,

- A is the name of the matrix
- a11 to a1n is the row elements of a matrix
- a11 to am1 is the column element of a matrix

## How to Calculate the Matrix?

For the **calculation of matrices**, the matrices calculator performs various operations like addition, subtraction, multiplication, determinant, and inverse. Let's see how to perform these basic matrix operations one by one with the help of examples.

### Matrix Addition:

To **add the two matrices**, first, the matrix equation solver checks whether both the matrices have the same order or not. If it has the same order then it adds the corresponding elements from the matrix. Suppose that matrix addition,

$$ A \;=\; \biggr( \begin{matrix} 1 & 2 \\ 3 & 4 \\ \end{matrix} \biggr), B \;=\; \biggr( \begin{matrix} 5 & 6 \\ 7 & 8 \\ \end{matrix} \biggr) $$

**Solution**:

$$ A + B \;=\; \biggr( \begin{matrix} 1 + 5 & 2 + 6 \\ 3 + 7 & 4 + 8 \\ \end{matrix} \biggr) \;=\; \biggr( \begin{matrix} 6 & 8 \\ 10 & 12 \\ \end{matrix} \biggr) $$

### Matrix Subtraction:

For the **subtraction of the matrix** same addition rule is followed in which crosspounding elements of matrices are subtracted, but it should maintain the order of the matrix.

$$ A \;=\; \biggr(\begin{matrix} 1 & 2 \\ 3 & 4 \\ \end{matrix} \biggr), B \;=\; \biggr(\begin{matrix} 5 & 6 \\ 7 & 8 \\ \end{matrix} \biggr) $$

$$ A - B \;=\; \biggr(\begin{matrix} 1 - 5 & 2 - 6 \\ 3 - 7 & 4 - 8 \\ \end{matrix} \biggr) \;=\; \biggr(\begin{matrix} -4 & -4 \\ -4 & -4 \\ \end{matrix} \biggr) $$

### Matrix Multiplication:

For the **multiplication of two matrices** A and B, the matrix calculator multiplies the elements of a row from matrix A by a column of matrix B. In the same way, the second-row elements of matrix A are multiplied by the column of matrix B. For this, suppose a matrix A and B.

$$ A \;=\; \biggr(\begin{matrix} 1 & 2 \\ 3 & 4 \\ \end{matrix} \biggr), B \;=\; \biggr(\begin{matrix} 2 & 0 \\ 1 & 2 \\ \end{matrix} \biggr) $$

$$ AB \;=\; \biggr(\begin{matrix}(1 . 2 + 2 . 1) & (1 . 0 + 2 . 2) \\ (3 . 2 + 4 . 1) & (3 . 0 + 4 . 2) \end{matrix} \biggr) $$

$$ =\; \biggr(\begin{matrix} 4 & 4 \\ 10 & 8 \\ \end{matrix} \biggr) $$

### Matrix Determinant:

For the **determinant** of the 2 by 2 matrix the matrix solution calculator uses cross multiplication method to solve the given matrix determinant. Let's take a matrix A for finding the determinant.

$$ A \;=\; \biggr(\begin{matrix} a & b \\ c & d \\ \end{matrix} \biggr) $$

$$ det\; (A) \;=\; ad - bc $$

In the same way, if you have a 3 by 3 matrix for the determinant then you use the expansion cofactor rule to find its determinant.

### Inverse of a Matrix

To find the solution of the **inverse matrix**, only two conditions are compulsory and the condition is when the given matrix is a square matrix and its determinant is not equal to zero. Such as:

$$ If\; det(A) \;=\; ad - cb\; ≠\; 0 $$

$$ A \;=\; \left( \begin{matrix} a & b \\ c & d \\ \end{matrix} \right) $$

$$ A^{-1} \;=\; \frac{1}{det\; (A)} \biggr(\begin{matrix} d & -b \\ -c & a \\ \end{matrix} \biggr) $$

In this method first element of the column and the second column's second element interchange their positions and the first, the second element, and the first column's first element signs have changed from positive to negative.

### Transpose of a Matrix:

In the **transposition of a matrix**, the matrix equation calculator changes the number of rows into columns, and columns become rows in the given matrix.

$$ A \;=\; \left( \begin{matrix} 1 & 2 \\ 3 & 4 \\ 5 & 6 \\ \end{matrix} \right) $$

$$ A^{T} \;=\; \left( \begin{matrix}1 & 3 & 5 \\ 2 & 4 & 6 \\ \end{matrix} \right) $$
