# matrix calculator

The matrix calculator allows to do calculations with matrices online.

### Matrix calculator, online calculus

#### Summary :

The matrix calculator allows to do calculations with matrices online.

matrix_calculator online

#### Description :

The matrix calculator allows for the matrix calculation from the cartesian coordinates.

The online matrix calculator allows for arithmetic operations on matrices, it allows to do sum, difference, product of matrices, multiplication of a matrix by a scalar, or again elevation of a matrix to a power. The matrix calculator allows you to use both literal and numeric elements. The matrix calculator specifies the different calculation steps

## Arithmetic operations using matrices

To perform the following calculation ((2,10),(2,10))*((3,2),(1,4))-((1,1),(2,3)) involving matrices enter matrix_calculator([[2;2];[10;10]]*[[3;1];[2;4]]-[[1;2];[1;3]]), after calculation, the result is returned.

## Matrices and literal coordinate calculation

A highlight of the matrix calculator is its ability to do literal calculation, ie symbolic calculation from letters.

To perform the following calculation ((a,a),(2*a,5*a))+((a,6*a),(a+3,a)) involving matrices containing letters, enter matrix_calculator([[a;2a];[a;5a]]+[[a;a+3];[6a;a]]), after calculation, the result is returned.

## Raise a matrix squared or at any power

The matrix calculator allows you to raise a matrix squared easily and quickly. So to calculate the square of a matrix like this one : ((2,10),(1,5))^2, just enter matrix_calculator([[2;10];[1;5]]^2), to obtain the result. The principle is the same for calculating a matrix at any power 3,4,5, ...

## Calculate the inverse of a matrix

The matrix calculator allows you to calculate the inverse of a square matrix, for example to calculate the the inverse of a matrix like this one : ((2,3),(1,5))^-1, just use the following syntax: matrix_calculator([[2;3];[1;5]]^-1), after calculation, the calculator gives the result.

#### Syntax :
