Linear Algebra is already a solved problem - there's no need to rewrite the many established C/C++/Fortran code that has been optimized for linear algebra over the last 40 years.

Why re-write what has already been done? Stand on the shoulders of giants.

Because we can do better. For example, look at Mir GLAS, written in D.

https://github.com/libmir/mir-glas

At a first glance, it looks like the way they're optimizing the BLAS/LAPACK implementations is by making it CPU architecture specific - the same game that IMKL plays. That's probably why they are reaching the same performance as MKL as well.

Good to see they aren't reinventing the wheel, and openly expressing inspiration from Numpy is also a nice touch.

1000s Kudos for Mir and Dlang. My language of choice.

Because 10k lines of D is easier to maintain than 20mb of assembler fortran mix. Plus you get all llvm niceties.

Removing compiling issues, keeping everything in one language. Plus, when you do, you find bugs. We've found a bunch in lapack implementing gonum (godoc.org/github.com/gonum/lapack)

My understanding is you can call C code from Crystal bindings. It doesn't seem like you need to rewrite the wheel :-)

You already have bindings to BLAS, in https://github.com/mverzilli/crystalla , though I'm not certain how mature and full fledged it is.

You can the same for any programming language or OR, so why bother creating new things.
