此函数返回数组上的1-D迭代器。 它的行为类似于Python的内置迭代器。
import numpy as np
a = np.arange(8).reshape(2,4)
print 'The original array:'
print a
print '\n'
print 'After applying the flat function:'
# returns element corresponding to index in flattened array
print a.flat[5]
其输出如下 -
The original array:
[[0 1 2 3]
[4 5 6 7]]
After applying the flat function:
5
