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.
