Hi,

I'm looking for some basic matrix/vector operations and other numeric stuff.

I spent quite a lot time in reading through the mir documentation, but i kinda miss the bigger picture. I'm not a Python user btw. (I know C,C++,C#,Matlab..).

I have also looked at the documentation of the lubeck package.

What i have seen right now reminds me of the saying "Real programmers can write FORTRAN in any language".

Is there a type to do matrix operations with nice syntax (e.g. using * operator for multiplication)?

Matrix/vector operations can be done with lubeck, which itself is built upon mir. mtimes is the one for matrix multiplication.

I would not bank on any changes in operator overloading (e.g. allowing an operator for matrix multiplication) any time soon.

I do have all that for my own use. I've never bothered to turn it into something others could use because I love the garbage collector, but that's a turnoff for others. But I'm more than happy to share if you're really interested. I'm also working on an R -> D compiler, but it's not helpful at this point.

It wouldn't take much to create a simple wrapper over mir/lubeck to do operator overloading. This is low-hanging fruit for someone that wants to contribute to the language. Until I win the lottery, I won't have time to do it myself.

I would actually like it to be garbage collected, because i would use it for some
skripts instead of matlab. Matlab is really horrible, but if you want to do something quick, e.g. analyse sensor data, you have everything you need in an easy to use interface. I think D could really shine in this area...

Yeah, i thought about that also... Is there any good article about mir/ndslice beside the documentation? I mean something more abstract, like a general overview.

Probably you should go for mir packages. But if you live with c++ linkage and matrix support of opencv is enough for your case, there is OpenCV binding for D.

Absolutely. In fact, it has been shining for me.

Not that I'm aware. I've not spent much time on it, since I already had my libraries working before Mir was a thing.
