det = m11 m22 m33 + m12 m23 m31 + m13 m21 m32 - m11 m23 m32 - m12 m 21 m33 - m13 m22 m31
The following calculator allows you to calculate the inverse for a 3x3 matrix. Enter the values into the matrix and then press "calc inverse " to display the result:
public double determinant() {
double value =
m00 m11 m22 + m01 m12 m20 + m02 m20 m21 - m00 m12 m21 - m01 m10 m22 - m02 m11 m20;
return value;
}
