If you do not like the shortcut, you can also find the inverse of a 3x3 matrix by using matrix row operations. One method that i learned for 3 by 3 determinants (and only 3 by 3) was to repeat the first two columns, calculate the three diagonals from upper left to lower right, add them, then from upper right to lower left, add them, and finally subtract the second number from the first.
Matrix $ B $ Is A $ 3 \Times 3 $ Square Matrix.
1 if a 3x3 matrix multiplied with a 3x3 matrix returns the transform of the second 3x3 matrix, what does a nonsquare matrix multiplied with 3x3 return? You trade flexibility with a little speed up. (this one has 2 rows and 2 columns) let us calculate the determinant of that matrix:
Find More Mathematics Widgets In Wolfram|Alpha.
Multiply the element a by the determinant of the 2×2 matrix obtained by eliminating the row and column where a is. This shortcut involves taking the reciprocal of the determinant of a 3x3 matrix, and then multiplying by the adjugate matrix. You can unroll the loops and take advantage of the fact that you handle 3x3 matrices and not nxn matrices.
