Arguments

A

An Expression or numeric matrix.

k

A positive integer.

object

A LambdaSumLargest object.

values

A list of numeric values for the arguments

Methods (by generic)

  • allow_complex(LambdaSumLargest): Does the atom handle complex numbers?

  • to_numeric(LambdaSumLargest): Returns the largest eigenvalue of A, which must be symmetric.

  • validate_args(LambdaSumLargest): Verify that the argument A is square.

  • get_data(LambdaSumLargest): Returns the parameter k.

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

Slots

k

A positive integer.
