Numpy

Numpy documentation states that the operator you apply performs element-wise multiplication.

但是，MATLAB中的 mtimes 会进行矩阵乘法

However, mtimes in MATLAB does matrix multiplication.

要进行验证，MATLAB逐元素乘法的语法会产生与numpy中相同的结果:

To verify, MATLAB syntax for element-wise multiplication produces the same result you see in numpy:

disp(x.'.*x)

     4    56    20    54     4
    56     9     7    42    80
    20     7     9   100     2
    54    42   100     1    40
     4    80     2    40    81
