A |
An Expression or numeric matrix. |
k |
A positive integer. |
object |
A LambdaSumLargest object. |
values |
A list of numeric values for the arguments |
allow_complex: Does the atom handle complex numbers?
to_numeric: Returns the largest eigenvalue of A, which must be symmetric.
validate_args: Verify that the argument A is square.
get_data: Returns the parameter k.
.grad: Gives the (sub/super)gradient of the atom w.r.t. each variable
kA positive integer.
