Arguments

x

An Expression or numeric matrix.

object

A OneMinusPos object.

values

A list of numeric values for the arguments

idx

An index into the atom.

Methods (by generic)

  • name(OneMinusPos): The name and arguments of the atom.

  • to_numeric(OneMinusPos): Returns one minus the value.

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

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

  • is_atom_convex(OneMinusPos): Is the atom convex?

  • is_atom_concave(OneMinusPos): Is the atom concave?

  • is_atom_log_log_convex(OneMinusPos): Is the atom log-log convex?

  • is_atom_log_log_concave(OneMinusPos): Is the atom log-log concave?

  • is_incr(OneMinusPos): Is the atom weakly increasing in the argument idx?

  • is_decr(OneMinusPos): Is the atom weakly decreasing in the argument idx?

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

Slots
