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 2 10 10 )⋅( 3 1 2 4 )−( 1 2 1 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 2⋅a a 5⋅a )+( a a+3 6⋅a 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 1 10 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 1 3 5 ) −1 ( , just use the following syntax: matrix_calculator( [[2;3];[1;5]] −1 [ ), after calculation, the calculator gives the result. The matrix calculator allows to do calculations with matrices online. Syntax : matrix_calculator(expression) Examples : matrix_calculator( [[2;2];[10;10]]⋅[[3;1];[2;4]]−[[1;2];[1;3]] [ ), , returns [[15;14];[43;41]] matrix_calculator( [[a;2a];[a;5a]]+[[a;a+3];[6a;a]] [ ), returns [[2*a;3+3*a];[7*a;6*a]] Calculate online with matrix_calculator (matrix calculator) See also Determinant calculator : determinant.
