Class Stream represents object stream, use IntStream, LongStream, DoubleStream for primitives.
To flatten double[][] use flatMapToDouble:
DoubleStream doubles = Stream.of(dm).flatMapToDouble(DoubleStream::of);from lightweight-stream-api.

That's all right. There are special methods to convert between Streams:
| from \ to | Stream | IntStream | LongStream | DoubleStream |
|---|---|---|---|---|
| Stream | map / flatMap | mapToInt / flatMapToInt | mapToLong / flatMapToLong | mapToDouble / flatMapToDouble |
| IntStream | mapToObj | map / flatMap | mapToLong | mapToDouble |
| LongStream | mapToObj | mapToInt | map / flatMap | mapToDouble |
| DoubleStream | mapToObj | mapToInt | mapToLong | map / flatMap |
from lightweight-stream-api.
