26 Sep 2019 I'm trying to optimize my code to the maximum performance, I have 3x3 matrix, I'm calculating the inverse using the function. matinv from the 

Setting up the Problem. Why would you ever need to find the inverse of a 3x3 matrix? Well, matrices and inverse matrices have lots of applications in geometry, the sciences, and especially

Before you work through this leaflet, you will need to know how to find the determinantand cofactorsof a 3× 3 matrix. If necessary you Inverse of a 3 by 3 Matrix As you know, every 2 by 2 matrix A that isn't singular (that is, whose determinant isn't zero) has an inverse, A−1, with the property that AA−1 = A−1A = I2 where I2 is the 2 by 2 identity matrix, 1 0 0 1. The inverse of a matrix is a matrix that multiplied by the original matrix results in the identity matrix, regardless of the order of the matrix multiplication.. Thus, let A be a square matrix, the inverse of matrix A is denoted by A-1 and satisfies:. A·A-1 =I. A-1 ·A=I. Where I is the identity matrix.

Processing

If the determinant is 0, the matrix has no inverse. Next, transpose the matrix by rewriting the first row as the first column, the middle row as the middle column, and the third row as the third column. Matrices, when multiplied by its inverse will give a resultant identity matrix. 3x3 identity matrices involves 3 rows and 3 columns. In the below Inverse Matrix calculator, enter the values for Matrix (A) and click calculate and calculator will provide you the Adjoint (adj A), Determinant (|A|) and Inverse of a 3x3 Matrix.
