numpy.hstack numpy.stack numpy.vstack numpy.stack函数的变量用于堆叠,以便水平生成单个数组。 例 import numpy as np a = np.array([[1,2],[3,4]]) print 'First array:' print a print '\n' b = np.array([[5,6],[7,8]]) print 'Second array:' print b print '\n' print 'Horizontal stacking:' c = np.hstack((a,b)) print c print '\n' 它会产生以下输出 First array: [[1 2] [3 4]] Second array: [[5 6] [7 8]] Horizontal stacking: [[1 2 5 6] [3 4 7 8]] numpy.stack numpy.vstack
