python矩阵转换为一维数组的实例
实例如下所示:
>>>fromcompiler.astimportflatten >>>X matrix([[1,17,13,221,289,169], [1,17,14,238,289,196], [1,17,15,255,289,225], [1,18,13,234,324,169], [1,18,14,252,324,196], [1,18,15,270,324,225], [1,19,13,247,361,169], [1,19,14,266,361,196], [1,19,15,285,361,225]]) >>>x=X.tolist() >>>x [[1,17,13,221,289,169], [1,17,14,238,289,196], [1,17,15,255,289,225], [1,18,13,234,324,169], [1,18,14,252,324,196], [1,18,15,270,324,225], [1,19,13,247,361,169], [1,19,14,266,361,196], [1,19,15,285,361,225]] >>>xx=flatten(x) >>>xx [1, 17, 13, 221, 289, 169, 1, 17, 14, 238, 289, 196, 1, 17, 15, 255, 289, 225, 1, 18, 13, 234, 324, 169, 1, 18, 14, 252, 324, 196, 1, 18, 15, 270, 324, 225, 1, 19, 13, 247, 361, 169, 1, 19, 14, 266, 361, 196, 1, 19, 15, 285, 361, 225]
