e1, e2 |
The Expression objects or numeric constants to subtract. |
object |
A NegExpression object. |
idx |
An index into the atom. |
arg_objs |
A list of linear expressions for each argument. |
dim |
A vector representing the dimensions of the resulting expression. |
data |
A list of additional data required by the atom. |
dim_from_args: The (row, col) dimensions of the expression.
sign_from_args: The (is positive, is negative) sign of the expression.
is_incr: The expression is not weakly increasing in any argument.
is_decr: The expression is weakly decreasing in every argument.
is_symmetric: Is the expression symmetric?
is_hermitian: Is the expression Hermitian?
graph_implementation: The graph implementation of the expression.
