WebYes, matrix A multiplied with it's inverse A-1 (if it has one, and matrix A is a square matrix) will always result in the Identity matrix no matter the order (AA^-1 AND A^ (-1)A will give I, so they are the same). However, matrices (in general) are not commutative. That means that AB (multiplication) is not the same as BA. WebWith help of this calculator you can: find the matrix determinant, the rank, raise the matrix to a power, find the sum and the multiplication of matrices, calculate the inverse matrix. Just type matrix elements and click the button. Leave extra cells empty to enter non-square matrices. You can use decimal fractions or mathematical expressions:
