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
