A good example of where Atila's concepts library would be helpful...

Hi All,
Can anyone guide me what is the problem with below code as
it throws error.
import std.stdio, mir.math.common: approxEqual;
static immutable x = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
static immutable y = [1, 3, 2, 5, 7, 8, 8, 9, 10, 12];
auto params = x.simpleLinearRegression(y);
writeln(params);
This should be in the Learn forum.
As far as I can tell, the problem is that x and y are both type
immutable(int[]), which it cannot handle. I tried just turning
them into slices, but that wasn't sufficient, I had to ensure
they were double as well (float would also work). Note that the
example in the document uses a y variable that is a floating
point type.

auto y = [1, 3, 2, 5, 7, 8, 8, 9, 10, 12].sliced!double;
auto params = x.simpleLinearRegression(y);
writeln(params);

Probably it is because of your browser cache, likely will be updated after a while. Also, on the mir.glas page, one of the lines says "matrix-vector operations %3 done, partially optimized for now". Another line says "l3 was moved to mir-glas", which is confusing because it should be at the mir-glas documentation page anyway. We don't have documentation for mir-glas library, only for mir (backports) package, which has mir.glas package. I don't know what to do with mir-glas, it is too good to be forgotten, but I don't see a commercial perspective in it.
