The inverse_matrix function allows to calculate online the inverse of a matrix.

inverse_matrix online

#### Description :

The calculator can calculate online the inverse of a square matrix. Let A and B be two square matrices, if B is the inverse of A, then A * B = I, I is the identity matrix. The matrix calculator may calculate the inverse of a matrix whose coefficients have letters or numbers, it is a formal matrix calculation calculator.

# Calculating the inverse of a square matrix

The calculator can calculate the inverse of a matrix with the results in exact form: to calculate the inverse of matrix (3,3,4),(1,2,0),(0,1,7), enter inverse_matrix([[3;1;0];[3;2;1];[4;0;7]]), after calculation, the result is returned.

The calculator allows symbolic calculations, it is possible to use letters as well to calculate the inverse of a matrix like this: ((a,3*a,4),(1,2*a,0),(0,c,a/2)), enter inverse_matrix([[a;1;0];[3a;2a;c];[4;0;a/2]]), after calculation, the result is returned.

The inverse_matrix function allows to calculate online the inverse of a matrix.

#### Syntax :

inverse_matrix(matrix)

#### Examples :

inverse_matrix([[3;1;0];[3;2;1];[4;0;1]]) returns [[2/7;-1/7;1/7];[1/7;3/7;-3/7];[-8/7;4/7;3/7]]
