WebApr 12, 2016 · The determinant is actually a function $\det: \mathbb{R}^{n\times n}\rightarrow \mathbb{R}: A\mapsto \det(A)$. So to each square matrix we can assign a real number. So clearly matrices and determinants are completely different. One of the most important features of a determinant is the following theorem: WebMatrices and determinants are used to perform various arithmetic operations involving an array of elements. Matrices are a rectangular array of elements that are represented in the form of rows and columns. And determinants are calculated for a matrix and it is a single numeric value that has been computed from this array of elements.
