Repository and documentation

Could be pronounced as key-math. The Kotlin Mathematics library was initially intended as a Kotlin-based analog to Python's NumPy library. Later we found that kotlin is much more flexible language and allows superior architecture designs. In contrast to numpy and scipy it is modular and has a lightweight core. The numpy-like experience could be achieved with kmath-for-real extension module.

Publications and talks


  • Provide a flexible and powerful API to work with mathematics abstractions in Kotlin-multiplatform (JVM, JS and Native) .
  • Provide basic multiplatform implementations for those abstractions (without significant performance optimization).
  • Provide bindings and wrappers with those abstractions for popular optimized platform libraries.


  • Be like NumPy. It was the idea at the beginning, but we decided that we can do better in API.
  • Provide the best performance out of the box. We have specialized libraries for that. Need only API wrappers for them.
  • Cover all cases as immediately and in one bundle. We will modularize everything and add new features gradually.
  • Provide specialized behavior in the core. API is made generic on purpose, so one needs to specialize for types, like for Double in the core. For that we will have specialization modules like kmath-for-real, which will give better experience for those, who want to work with specific types.
