5.1.20 diff
Syntax:
diff ( poly_expression, ring_variable )
diff ( vector_expression, ring_variable )
diff ( ideal_expression, ring_variable )
diff ( module_expression, ring_variable )
diff ( matrix_expression, ring_variable )
Type:
- the same as the type of the first argument
Syntax:
diff ( ideal_expression, ideal_expression )
Type:
- matrix
Purpose:
- computes the partial derivative of a polynomial object by a ring variable
(first forms)
respectively differentiates each polynomial (1..n) of the second ideal
by the differential operator corresponding to each polynomial (1..m) in the first
ideal, producing an m x n matrix.
Example:
See
contract;
ideal;
jacob;
matrix;
module;
poly;
var;
vector.
