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: The dimensions of the atom.

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

  • get_data: The original expression.

  • is_atom_convex: Is the original expression convex?

  • is_atom_concave: Is the original expression concave?

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

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

  • is_quadratic: The atom is quadratic.

  • .grad: 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.
