arrays with the same number of rows and columns). If we use np.add with two same-sized arrays, then Numpy add will add the elements of the second array to the elements of the first array, in an element-wise fashion.

这个reduce与ufunc.reduce(比如说add.reduce)相比的优势在于它利用了广播法则,避免了创建一个输出大小乘以向量个数的参数数组。 8 用字符串索引 参见 RecordArray。 线性代数 继续前进,基本线性代数包含在这里。 简单数组运算 参考numpy文件夹中的linalg.py获得更多信息 >>> from numpy import * >>> from nump...
