numpy-rms 0.6.0

A fast python library for calculating the RMS of a NumPy array

numpy-rms: a fast function for calculating a series of Root Mean Square (RMS) values

• Written in C and takes advantage of AVX (on x86-64) or NEON (on ARM) for speed
• The fast implementation is tailored for C-contiguous 1-dimensional and 2-dimensional float32 arrays

Installation

$ pip install numpy-rms

Usage

import numpy_rms
import numpy as np

arr = np.arange(40, dtype=np.float32)
rms_series = numpy_rms.rms(arr, window_size=10)
print(rms_series.shape)  # (4,)
