WebThe determinant can be viewed as a function whose input is a square matrix and whose output is a number. 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 ... WebThe determinant can be negative or zero. A linear map can stretch and scale a volume, but it can also reflect it over an axis. Whenever this happens, the sign of the determinant changes from positive to negative, or from negative to positive. A negative determinant means that the volume was mirrored over an odd number of axes.
