As noted above, NumPy arrays behave a lot like other Python objects, for the sake of convenience. For instance, they can be indexed like lists; arr[0] accesses the first element of a NumPy array.

Numpy Arrays Basic Ways to Build Arrays. We can cast an ordinary python list as a NumPy one-dimensional array. import numpy as np my_list = [1, 2, 3] np. array (my_list) # cast a list into a 1D array.

NumPY also uses external standard, optimized libraries written in C or FORTRAN to handle many of the actual manipulations on these array data types. This is handled by libraries like BLAS or lapack.

We really recommend that fans of Python and NumPy give this one a look over! Posted in Arduino Hacks, Microcontrollers Tagged fft, matrix, microcontroller, micropython, numpy, python, ulab.
