感觉numpy.hstack()和numpy.column_stack()函数略有相似,numpy.vstack()与numpy.row_stack()函数也是挺像的. stackoverflow上也有类似的讨论,在这里numpy vstack vs. column_stack. 给一个相关函数的列表: stack() Join a sequence of arrays along a new axis. hstack() Stack arrays in sequence horiz…
定义: Stack arrays in sequence horizontally (column wise). Take a sequence of arrays and stack them horizontally to make a single array. Rebuild arrays divided by hsplit. This function continues to be supported for backward compatibility, but you shoul…
