multik VS kotlin-flow-extensions

If you need a simpler array syntax, have a look at the official multi dimensional array library for Kotlin: https://github.com/Kotlin/multik

for JVM https://github.com/Kotlin/multik

Multik (NumPy analogue) - Multidimensional array library for Kotlin.

To work with matrices, I'm using multik, a multidimensional array library for Kotlin. It has been publicly released recently, and you can read more about it on the Kotlin blog.

Can the benchmark add the recent https://github.com/Kotlin/multik And https://github.com/Kotlin/kotlin-numpy

I don't know, why I'm downvoted here, but it is very relevant if the library provide the operators you need or if you have to implement them yourself. If Kotlin Flow is enough, then use it. From experience you don't have to go to far to miss operators from Reactor or RxJava. Maybe some day additional libraries like https://github.com/akarnokd/kotlin-flow-extensions will fill the gap, but for the time being Reactor or RxJava offer a lot more for (not trivial) real world use cases.

Why do you want to keep Flow such a small library? It could be an attractive alternative to RxJava or Reactor, but it misses many useful operators today. On the other hand it brings a lot more operatores than would be required as a foundation for other frameworks (likeKotlin Flow Extensions). From my point of view Flow stays in the middleground with no good reason.
