Description Calculates determinant of input matrix
Arguments and Return Values Parameters: A square matrix (dimensions [n, n, 1]) Return Value: A double-precision value specifying the determinant of the input
Usage Syntax: det(matrix) Note that, due to roundoff error, the calculated determinant of a singular matrix may not be exactly zero. When det() is entered without any arguments, it prints its description, as shown below.
