在numpy库中,对于矩阵的合并操作用两种方法:行合并:np.row_stack()列合并:np.column_stack()具体操作见下面的程序: >>> import numpy as np>>>...-1)>>> barray([[16, 17, 18, 19],[20, 21, 22, 23],[24, 25, 26, 27],[28, 29, 30, 31]])>>> test=np.row_stack...13, 14, 15],[16, 17, 18, 19],[20, 21, 22, 23],[24, 25, 26, 27],[28, 29, 30, 31]])>>> test=np.column_stack
