# Matrix Calculator

## Solve matrices step by step

This calculator will add, subtract, multiply, divide, and raise to power two matrices, with steps shown. It will also find the determinant, inverse, rref (reduced row echelon form), null space, rank, eigenvalues, and eigenvectors and will multiply the matrix by a scalar.

At the heart of a multitude of computations in mathematics, science, and engineering lies the matrix. This is a rectangular arrangement of elements structured into rows and columns. Mastery over matrices and the ability to proficiently handle their manipulations are critical skills in these domains. Our Matrix Calculator is designed precisely for this purpose. It assists you in performing a broad spectrum of matrix calculations, doing so with efficiency and precision.

The matrix calculator can be used to solve or "help" solve systems of linear equations, saving you the labor of manual calculation.

## What Is a Matrix in Math?

In mathematics, a matrix is essentially a grid of numbers placed in rows and columns. These numbers are known as elements. For example, a simple 2x2 matrix might look like this:

$$A=\left[\begin{array}{cc}1&2\\3&4\end{array}\right]$$In this matrix $$$A$$$, "1," "2," "3," and "4" are the elements. The matrix has 2 rows and 2 columns, so we describe it as a 2x2 matrix.

A more complex 3x3 matrix could be:

$$B=\left[\begin{array}{ccc}2&7&1\\9&3&8\\6&4&5\end{array}\right]$$Here, $$$B$$$ is a matrix with 3 rows and 3 columns, hence termed as a 3x3 matrix, and numbers from $$$1$$$ to $$$9$$$ are the elements of the matrix.

Matrices are extremely powerful mathematical tools used for various purposes, such as solving systems of linear equations, representing linear transformations, and handling graph data structures in computer science. They also find significant applications in other disciplines like physics, engineering, computer graphics, and statistics.
