Module ndarray_ext 

Extended ndarray operations for scientific computing

This module provides additional functionality for ndarray to support the advanced array operations necessary for a complete SciPy port. It implements core NumPy-like features that are not available in the base ndarray crate.

Modules

elementwise

Element-wise mathematical operations with SIMD acceleration (abs, sqrt, etc.) SIMD-accelerated element-wise mathematical operations

indexing

Advanced indexing operations (NumPy-like boolean masking, fancy indexing, etc.) Advanced indexing operations for ndarray

manipulation

Array manipulation operations (flip, roll, tile, repeat, etc.) Array manipulation operations similar to NumPy’s array manipulation routines

matrix

Matrix operations (eye, diag, kron, etc.) Matrix operations for ndarray

preprocessing

Data preprocessing operations with SIMD acceleration (normalization, standardization) SIMD-accelerated preprocessing operations for array normalization and standardization

reduction

Array reduction operations with SIMD acceleration (argmin, argmax, etc.) Array reduction operations with SIMD acceleration

stats

Statistical functions for ndarray arrays (mean, median, variance, correlation, etc.) Statistical functions for ndarray arrays
