x |
An Expression or numeric matrix. |
k |
The number of largest values to sum over. |
object |

to_numeric
: The sum of the k
largest entries of the vector or matrix.
validate_args
: Check that k
is a positive integer.
dim_from_args
: The atom is a scalar.
sign_from_args
: The sign of the atom.
is_atom_convex
: The atom is convex.
is_atom_concave
: The atom is not concave.
is_incr
: The atom is weakly increasing in every argument.
is_decr
: The atom is not weakly decreasing in any argument.
get_data
: A list containing k
.
.grad
: Gives the (sub/super)gradient of the atom w.r.t. each variable
x
An Expression or numeric matrix.
k
