You will be using Python 3. Avoid using for-loops and while-loops, unless you are explicitly told to do so. Do not modify the (# GRADED FUNCTION [function name]) comment in some cells. Your work would not be graded if you change this. Each cell containing that comment should only ...

Numpy is the main package for scientific computing in Python. It is maintained by a large community (www.numpy.org). In this exercise you will learn several key numpy functions such as np.exp, np.log, and np.reshape. You will need to know how to use these functions for future assignmen...
NumPy 是基于 Python 的通用语言。NumPy 的优势在于访问 Python 库,包括:SciPy,Matplotlib,Pandas,OpenCV等。此外,Python 经常作为嵌入式脚本语言嵌入到其他软件中,也可以在那里使用 NumPy。 MATLAB 数组切片使用值传递语义,采用延迟写入复制方案以防止创建副本,直到需要为止。切片操作复制数组的部分。 NumPy 数组切片使用...

這篇文章我們來看看如何用 NumPy 來加速 Python 的效能,並且用一個簡單的例子來說明。 本文要介紹的是 NumPy 當中一種叫做「Boolean array indexing」的技巧,官方文件的連結如下: Boolean array indexingnumpy.org/doc/stable/user/basics.indexing.html#boolean-array-indexing ...

第二部分:Python Basics with Numpy 该内容来自吴恩达的task2的numpy练习 Avoid using for-loops and while-loops, unless you are explicitly told to do so.就是少用或者不用循环,防止时间复杂度过高。 math库的方法输入一般是实数,而numpy输入一般是矩阵或者向量,所以numpy更适合DL 在anaconda jupyter上运行代码...
