SigmaMax-class: The SigmaMax class.

Description

The maximum singular value of a matrix.

Usage

SigmaMax(A = A)

# S4 method for SigmaMax to_numeric(object, values)

# S4 method for SigmaMax size_from_args(object)

# S4 method for SigmaMax sign_from_args(object)

# S4 method for SigmaMax is_atom_convex(object)

# S4 method for SigmaMax is_atom_concave(object)

# S4 method for SigmaMax is_incr(object, idx)

# S4 method for SigmaMax is_decr(object, idx)

# S4 method for SigmaMax graph_implementation(object, arg_objs, size, data = NA_real_)

Arguments

A

An '>Expression or matrix.

object

A '>SigmaMax object.

values

A list of arguments to the atom.

idx

An index into the atom.

arg_objs

A list of linear expressions for each argument.

size

A vector with two elements representing the size of the resulting expression.

data

A list of additional data required by the atom.

Methods (by generic)

  • to_numeric: The largest singular value of A.

  • size_from_args: The atom is a scalar.

  • sign_from_args: The atom is positive.

  • is_atom_convex: The atom is convex.

  • is_atom_concave: The atom is concave.

  • is_incr: The atom is not monotonic in any argument.

  • is_decr: The atom is not monotonic in any argument.

  • graph_implementation: The graph implementation of the atom.

Slots

A

An '>Expression or numeric matrix.
