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 .
