Determinants of 3x3 matrices
WebSep 16, 2024 · Theorems 3.2.1, 3.2.2 and 3.2.4 illustrate how row operations affect the determinant of a matrix. In this section, we look at two examples where row operations are used to find the determinant of a large matrix. Recall that when working with large matrices, Laplace Expansion is effective but timely, as there are many steps involved.

WebAs another hint, I will take the same matrix, matrix A and take its determinant again but I will do it using a different technique, either technique is valid so here we saying what is the determinant of the 3X3 Matrix A and we can is we can rewrite first two column so first column right over here we could rewrite it as 4 4 -2 and then the second column right …
Webyou can unroll the loops and take advantage of the fact that you handle 3x3 matrices and not nxn matrices. With this optimization you get rid of the determination of the size of the matrix. You trade flexibility with a little speed up. You can simply write down the concrete formulas for each cell of the result matrix.
