How to take inverse of 3x3 matrix
WebTo obtain the inverse of 3x3 matrix R R we apply the same method as in example 1. Thus, let us start by rewriting R along with the identity matrix to start the inversion and solve through matrix row operations as follows: Equation 18: Finding the inverse of matrix R And so, the final inverse of matrix R R is: Equation 19: Inverse of matrix R WebThe inverse of a matrix $ A $ is $ A^{ β 1 } $, such that multiplying the matrix with its inverse results in the identity matrix, $ I $. In this lesson, we will take a brief look at what an β¦
