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
This flowgraph shows the two usecases of the Argmax block. The top case shows how the max_inp output works. The bottom case shows how the max_vec output works.
This flowgraph can be downloaded from Media:Argmax.grc.
