How do I find the index of the max value in a vector from GRC?
The max_xx block outputs the max value, but not its
index, despite what it's documentation says:

"Data is passed in as a vector of length  from multiple input sources. It will look through these streams of  data items and output two streams. Stream 0 will contain the index value in the vector where the maximum value occurred."


I checked the code template for max (GR v3.7.3), and it doesn't even
seem to retain the index of the max it reports.

Ed,

Yeah, this block does not match the description. It simply outputs the maximum value for a given vector of samples. I'm going to fix this now since I'm about to push a few other changes.

I can see a use for having the block have an optional secondary stream with the index value, though.
