# KMath
|
||||
Could be pronounced as `key-math`.
|
||||
The Kotlin MATHematics library is intended as a Kotlin-based analog to Python's `numpy` library. In contrast to `numpy` and `scipy` it is modular and has a lightweight core.
|
||||
|
||||
# Goal
|
||||
* Provide a flexible and powerful API to work with mathematics abstractions in Kotlin-multiplatform (JVM and JS for now and Native in future).
|
||||
* Provide basic multiplatform implementations for those abstractions (without significant performance optimization).
|
||||
* Provide bindings and wrappers with those abstractions for popular optimized platform libraries.
|
||||
|
||||
## Non-goals
|
||||
* Be like Numpy. It was the idea at the beginning, but we decided that we can do better in terms of API.
|
||||
* Provide 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 `for-real`, which will give better experience for those, who want to work with specific types.

## Multi-platform support
|
||||
|
||||
KMath is developed as a multi-platform library, which means that most of interfaces are declared in the [common module](kmath-core/src/commonMain).
|
||||
Implementation is also done in the common module wherever possible. In some cases, features are delegated to
|
||||
platform-specific implementations even if they could be done in the common module for performance reasons.
|
||||
Currently, the JVM is the main focus of development, however Kotlin/Native and Kotlin/JS contributions are also welcome.

|
||||
## Performance
|
||||
|
||||
Calculation performance is one of major goals of KMath in the future, but in some cases it is not possible to achieve
|
||||
both performance and flexibility. We expect to focus on creating convenient universal API first and then work on
|
||||
increasing performance for specific cases. We expect the worst KMath benchmarks will perform better than native Python,
|
||||
but worse than optimized native/SciPy (mostly due to boxing operations on primitive numbers). The best performance
|
||||
of optimized parts should be better than SciPy.

### Dependency
|
||||
|
||||
Working builds can be obtained here: [](https://jitpack.io/#altavir/kmath).
|
||||
|
||||
### Development
|
||||
|
||||
The project is currently in pre-release stage. Nightly builds can be used by adding an additional repository to the Gradle config like so:
|
||||
|
||||
```groovy
|
||||
repositories {
|
||||
maven { url = "http://npm.mipt.ru:8081/artifactory/gradle-dev" }
|
||||
mavenCentral()
|
||||
}
|
||||
```
|
||||
|
||||
or for the Gradle Kotlin DSL:
|
||||
|
||||
```kotlin
|
||||
repositories {
|
||||
maven("http://npm.mipt.ru:8081/artifactory/gradle-dev")
|
||||
mavenCentral()
|
||||
}
|
||||
```
|
||||
|
||||
Then use a regular dependency like so:
|
||||
|
||||
```groovy
|
||||
api "scientifik:kmath-core-jvm:0.1.3-dev"
|
||||
```
|
||||
|
||||
or in the Gradle Kotlin DSL:
|
||||
|
||||
```kotlin
|
||||
api("scientifik:kmath-core-jvm:0.1.3-dev")
|
||||
```
|
||||
|
||||

|

Gradle `5.2+` is required for multiplatform artifacts.
