How To Vectorize An Image In Coreldraw What is the most efficient way to map a function over a numpy array? i am currently doing: import numpy as np x = np.array ( [1, 2, 3, 4, 5]) # obtain array of square. Is it a good idea to vectorize the code? what are good practices in terms of when to do it? what happens underneath?.

Bear in mind that np.vectorize doesn't really give any performance benefit over a plain list comprehension you'll still end up looping in python rather than c. The purpose of np.vectorize is to transform functions which are not numpy aware (e.g. take floats as input and return floats as output) into functions that can operate on (and return) numpy arrays. Here's my vectorization of your function. i worked from the inside out, and commented out earlier versions as i went along. so the first loop that i vectorized has.

What is the difference between vectorize and frompyfunc in numpy? both seem very similar. what is a typical use case for each of them? edit: as joshadel indicates, the class vectorize seems to be. I'd appreciate some help in finding and understanding a pythonic way to optimize the following array manipulations in nested for loops: def func(a, b, radius): "return 0 if a>b, otherwise. I was expecting vectorize and guvectorize to be almost similar in speedup but while njit and guvectorize are almost equal to each other in time, vectorize is ~2 and ~10 times slower than guvectorize and njit respectively. With the gcc compiler, the ftree vectorize option turns on auto vectorization, and this flag is automatically set when using o3. to what level does it vectorize?.
