If n is the number of rows and columns in the matrix (remember, we are dealing with square matrices), we can call our matrix an n × n matrix. The simplest square matrix is a 1 × 1 matrix, which isn't very interesting since it contains just ... In mathematics, the determinant is a scalar value that is a function of the entries of a square matrix. It characterizes some properties of the matrix and the linear map represented by the matrix. In particular, the determinant is nonzero if and only if the matrix is invertible and the linear map represented by the matrix is an isomorphism. The determinant of a product of matrices is the product of their determinants (the preceding property is a corollary of this one). The determinan… the photocaptionist
