WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: How to find the determinant of a 6x6 … WebAug 8, 2024 · In our example, the determinant of the matrix = 4 * 2 - 7 * 6 = -34. This determinant is called the minor of the element we chose in our original matrix. [5] In this case, we just found the minor of a 11. 5 Multiply the answer by your chosen element.

WebCareful though. Some row operations affect the value of the determinant. BUT! The row operation "add a multiple of one row to another row" does not affect the determinant at all. So use that row operation to turn your matrix into an upper triangular matrix. Then the determinant is simply the product of the numbers along the main diagonal.

WebFor example, 1e6*n is bigger than 0.0001*n^2 for all n < 1e5. – Gene Feb 19, 2024 at 7:16 You can be more specific and say something like "LU Decomposition and Bareiss are faster than Coppersmith-Winograd to find the determinant of an nxn matrix, when n < some_big_constant". Of course that requires some work to find out the big constant. – Stef
