按照行连接两个矩阵,就是把两矩阵上下相加,要求列数相等,类似于pandas中的concat()函数。 np.c_是列连接两个矩阵,就是把两矩阵左右相加,要求行数相等,类似于pandas中的merge()函数。 举个例子 1 2 11 12 13 14 15 16 17 18 19 20 21 22 23 import as np a = nparray([1, 2...
NumPy 1.26 中文文档(六) 原文:numpy.org/doc/ numpy.ma 模块的常量 原文:numpy.org/doc/1.26/reference/maskedarray.baseclass.html 除了MaskedArray类之外,numpy.ma模块还定义了几个常量。 nu
Notice that this is the same as if we had used concatenatewithoutspecifying theaxis. By default, the np.concatentate function setsaxis = 0. Concatenate numpy arrayshorizontally Finally, let’s concatenate the two arrays horizontally. To do this, we need to setaxis = 1. ...
Misc: concat, permute_dims, pow. In numpy.linalg: tensordot, matmul. (gh-25086) New unique_* functions The numpy.unique_all, numpy.unique_counts, numpy.unique_inverse, and numpy.unique_values functions have been added. They provide functionality of numpy.unique with different sets of flags....
