# 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

rms_series = numpy_rms.rms(arr, window_size=10)

print(rms_series.shape)  # (4,)

```
