Mir

Generic Numerical Library for Science and Machine Learning.

Separated Mir Projects
  • Mir Algorithm - Multidimensional arrays (ndslice), iterators, algorithms.
  • Mir Random - Professional Random Number Generators
  • Mir GLAS - Linear Algebra Library (Experimental, not supported for now)
  • Mir BLAS - Bindings to libraries with CBLAS API like OpenBLAS and Intel MKL.
  • Mir LAPACK - Bindings to libraries with LAPACK API like OpenBLAS and Intel MKL.
  • Mir Optim - Nonlinear Solvers.
  • Mir CPUID - CPU Identification routines (less buggy then Phobos).

Example

/+dub.sdl:
dependency "mir" version="~>3.1.0"
+/
import std.stdio;
import mir.combinatorics;
void main(string[] args)
{
    writeln([1, 2].combinations);
}

Fast setup with the dub package manager

Latest version

Dub is the D's package manager. You can create a new project with:

dub init 

Now you need to edit the

dub.json
add
mir
as dependency.
{
    ...
    "dependencies": {
        "mir": "~>"
    },
    "dflags-ldc": ["-mcpu=native"]
}

Now you can create an

app.d
file in the
source
folder and run your code with
dub --compiler=ldmd2
Flag
--build=release
and can be added for a performance boost:
dub --compiler=ldmd2 --build=release

ldmd2
is a shell on top of LDC (LLVM D Compiler).

"dflags-ldc": ["-mcpu=native"]
allows LDC to optimize Mir for your CPU.
