Let’s then do some practice. 然后让我们做一些练习。 I’m first going to define two one-dimensional arrays,called lower case x and lower case y. 我首先要定义两个一维数组,叫做小写x和小写y。 And I’m also going to define two two-dimens ...
I can then define a new array called z2, which is just z1 with one added to every single element of the array. 然后我可以定义一个名为z2的新数组,它只是z1,数组的每个元素都添加了一个。 We can now look at these two arrays to see what their contents are. 现在我们可以看看这两个数组,...

It provides a highly efficient interface to create and interact with multi-dimensional arrays. Nearly every other package in the SciPy stack uses or integrates with NumPy in some way. NumPy arrays are the equivalent to the basic array data structure in MATLAB. With NumPy arrays, you can do ...
