5.1.19 det

Syntax:
det ( intmat_expression )
det ( matrix_expression )
det ( module_expression )
Type:
int, resp. poly
Purpose:
returns the determinant of a square matrix. A module is considered as a matrix. The applied algorithms depend on type of input. If the input is a module or matrix with symbolic entries the Bareiss algorithm is used. In the other cases the chinese remainder algorithm is used. For large sparse problems the input as a module has advantages.
Example:
 
See intmat; matrix; minor.
