Eclipse January

Eclipse January is a set of libraries for handling numerical data in Java. It is inspired in part by NumPy and aims to provide similar functionality.

Why use it?

• Familiar. Provide familiar functionality, especially to NumPy users.
• Robust. Has test suite and is used in production heavily at Diamond Light Source.
• No more passing double[]. IDataset provide a consistent object for basing APIs on with significantly improved clarity over using double arrays or similar.
• Optimized. Optimized for speed and getting better all the time.
• Scalable. Allows handling of data sets larger than available memory with "Lazy Datasets".
• Focus on your algorithms. By reusing this library it allows you to focus on your code.

Browse through the examples:

• Basic Example show simple concepts for array creation, maths and slicing.
• NumPy Examples show how common NumPy constructs map to Eclipse Datasets.
• Slicing Examples demonstrate slicing, including how to slice a small amount of data out of a dataset too large to fit in memory all at once.
• Error Examples demonstrate applying an error to datasets.
• Iteration Examples demonstrate a few ways to iterate through your datasets.
• Lazy Examples demonstrate how to use datasets which are not entirely loaded in memory.
