Compares vectors from multiple streams and determines the index in the vector and stream number where the maximum value occurred.
Data is passed in as a vector of length vlen from multiple input sources. The block analyzes the input streams of data items and outputs two streams:
- max_vec: Stream 0 will contain the index value in the vector where the maximum value occurred. This output is of short data type.
- max_inp: Stream 1 will contain the number of the input stream that held the maximum value. This output is of short data type.
Parameters
- IO Type
- Supported data types
- Float
- Int
- Short
- Num Inputs
- Number of input streams to include in the operation
- Vec Length
- Length of the vector
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.
