Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.

Exponentiates a complex stream with an integer exponent. This block raises a complex stream to an integer exponent.

NOTE: The algorithm uses iterative multiplication to achieve exponentiation, hence it is O(exponent). Therefore, this block could be inefficient for large exponents.

Parameters

(R): Run-time adjustable

Exponent (R)
Exponent that the stream is raised to. Must be a positive integer.
Num Ports
Number of input streams to apply the operation on.
