Projects based on Mir


API can be found here. Read also the Mir blog.


  • mir.ndslice Multidimensional Random Access Ranges and Arrays
  • mir.sparse Sparse Tensors
  • Sparse - DOK format
  • Different ranges for COO format
  • CompressedTensor - CSR/CSC formats
  • mir.sparse.blas - Sparse BLAS for CompressedTensor
  • mir.model.lda.hoffman - Online variational Bayes for latent Dirichlet allocation (Online VB LDA) for sparse documents. LDA is used for topic modeling.
  • mir.combinatorics Combinations, combinations with repeats, cartesian power, permutations.
  • mir.las.sum Functions and Output Ranges for Summation Algorithms. Works with user-defined types.
  • Precise algorithm: improved analog of Python's fsum
  • Pairwise algorithm: fast version for Input Ranges
  • Kahan, KBN, and KB2 algorithms

In progress

  • mir.random - non-uniform RNGs.
  • mir.glas - Generic Linear Algebra Subroutines.

Fast setup with the dub package manager

Latest version Latest version Dub downloads

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

dub init <project-name>

Now you need to edit the dub.json add mir as dependency and set its targetType to executable.

	"dependencies": {
		"mir": "~><current-version>"
	"targetType": "executable",
	"dflags-ldc": ["-mcpu=native"]

Now you can create a main file in the source and run your code with


Flags --build=release and --compiler=ldmd2 can be added for a performance boost:

dub --build=release --compiler=ldmd2

ldmd2 is a shell on top of LDC (LLVM D Compiler). "dflags-ldc": ["-mcpu=native"] allows LDC to optimize Mir for your CPU.

See our TODO List. Mir is very young and we are open for contributing to source code, documentation, examples and benchmarks.
