Ah, you're right. I use it in other places where it hasn't
been an issue.
I can do it with an allocation (below) using the built-in
syntax, but not sure how do-able it is without an allocation
(Ilya would know better than me).
/+dub.sdl:
dependency "lubeck" version="~>1.1.7"
dependency "mir-algorithm" version="~>3.7.28"
+/
import mir.ndslice;
import lubeck;
void main() {
auto a = [2.1, 1.0, 3.2, 4.5, 2.4, 3.3, 1.5, 0,
2.1].sliced(3, 3);
auto b = a * a.transposed.slice;
}
Thanks. I somehow missed the whole point of "a * a.transposed"
not working because "a.transposed" is not allocated.
In the same time, the SliceKind isn't matter for assignment
operations:
auto b = a.slice; // copy a to b
b[] *= a.transposed; // works well
