Numpy Extension

This Python package extends the functionality of numpy by introducing additional methods for data manipulation, and a specialized format for reading and writing numpy arrays.

Features

• Read NDArray in Need with Keys: Using a key to load the required array without load all.
• Array Mapping and Transformation Functions: Functions to apply operations across arrays, adjust their ranges, and produce linearly spaced values with specific properties.

Installation

pip install numpy_ext

Usage

Transformation Functions

• apply_from_axis: Apply a function to slices of an array along a specified axis.
• map_range: Transform elements in an array to a specified range.
• map_ranges: Transform elements in an array to multiple specified ranges based on conditions.
• linspace_at: Generate linearly spaced numbers for given indices.
• linspace_cumprod_at: Generate a cumulative product series for linearly spaced values at specific indices.

Save and Load Utilities

• savek: Save multiple numpy arrays to a custom binary format .npk.
• loadk: Load arrays from a .npk file and read in need for easy access.
