Arguments

x

An Expression or numeric vector.

P

An Expression, numeric matrix, or vector.

expr

The original Expression.

object

A SymbolicQuadForm object.

idx

An index into the atom.

values

A list of numeric values for the arguments

Methods (by generic)

• dim_from_args(SymbolicQuadForm): The dimensions of the atom.

• sign_from_args(SymbolicQuadForm): The sign (is positive, is negative) of the atom.

• get_data(SymbolicQuadForm): The original expression.

• is_atom_convex(SymbolicQuadForm): Is the original expression convex?

• is_atom_concave(SymbolicQuadForm): Is the original expression concave?

• is_incr(SymbolicQuadForm): Is the original expression weakly increasing in argument idx?

• is_decr(SymbolicQuadForm): Is the original expression weakly decreasing in argument idx?

• is_quadratic(SymbolicQuadForm): The atom is quadratic.

• .grad(SymbolicQuadForm): Gives the (sub/super)gradient of the atom w.r.t. each variable

Slots

x

An Expression or numeric vector.

P

An Expression, numeric matrix, or vector.

original_expression

The original Expression.
