Multiplies the input by a scalar constant. The "Fast" refers to the performance of the block.
output = input * scalar constant
See Multiply_Const for a vector multiply block.
Note: This block uses VOLK (Vector-Optimized Library of Kernels) to improve execution speed.
Parameters
(R): Run-time adjustable
- Constant (R)
- Scalar constant
Example Flowgraph
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.
