# Apatite
|
||||
|
||||
Apatite is meant to be a collecion of mathmatical and scientific computing algorithms for the Crystal programming language. I don't expect it to ever reach the level of completeness as numpy, but hopefully it can save some people the trouble of implementing these methods on their own.
|
||||
Apatite is a collection of mathematical and scientific algorithms. Currently it implements the API from Ruby's `Matrix` class for both `Matrix` and `Vector`. This API will be added to as needs arise. The goal is for this project to eventually contain everything you could get from SciPy, but in pure Crystal.

<h1>Apatite</h1>
|
||||
|
||||
<p>Apatite is meant to be a collecion of mathmatical and scientific computing algorithms for the Crystal programming language. I don't expect it to ever reach the level of completeness as numpy, but hopefully it can save some people the trouble of implementing these methods on their own.</p>
|
||||
<p>Apatite is a collection of mathematical and scientific algorithms. Currently it implements the API from Ruby's <code>Matrix</code> class for both <code>Matrix</code> and <code>Vector</code>. This API will be added to as needs arise. The goal is for this project to eventually contain everything you could get from SciPy, but in pure Crystal.</p>
