Methods (by generic)

  • name: The name and arguments of the atom.

  • to_numeric: Returns the infinity norm of x.

  • allow_complex: Does the atom handle complex numbers?

  • sign_from_args: The atom is always positive.

  • is_atom_convex: The atom is convex.

  • is_atom_concave: The atom is not concave.

  • is_atom_log_log_convex: Is the atom log-log convex?

  • is_atom_log_log_concave: Is the atom log-log concave?

  • is_incr: Is the composition weakly increasing in argument idx?

  • is_decr: Is the composition weakly decreasing in argument idx?

  • is_pwl: Is the atom piecewise linear?

  • get_data: Returns the axis.

  • .domain: Returns constraints describing the domain of the node

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

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