Arguments

arg1	The first Expression in the maximum operation.
arg2	The second Expression in the maximum operation.
...	Additional Expression objects in the maximum operation.
object	A MaxElemwise object.
values	A list of numeric values for the arguments
idx	An index into the atom.

Methods (by generic)

• to_numeric(MaxElemwise): The elementwise maximum.

• sign_from_args(MaxElemwise): The sign of the atom.

• is_atom_convex(MaxElemwise): The atom is convex.

• is_atom_concave(MaxElemwise): The atom is not concave.

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

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

• is_incr(MaxElemwise): The atom is weakly increasing.

• is_decr(MaxElemwise): The atom is not weakly decreasing.

• is_pwl(MaxElemwise): Are all the arguments piecewise linear?

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

Slots

arg1

The first Expression in the maximum operation.

arg2
