- sorry. erm.. what does the determinant means or functions in matrices , math? thanks..
There's a theorem that says that the following statements about an arbitrary ##n\times n##-matrix ##A## are equivalent:why we want to get the determinant?
In applications, the determinant can used (in 2-D) to compute the "oriented" area of a parallelogram whose sides are given by 2 row vectors. In higher dimensions, it can be used to compute an "oriented" volume.why we want to get the determinant?
