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

inverse_matrix online

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.

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.

inverse_matrix(matrix)

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]]`
