1 Numpy Import

2 ndarray

One dimensional array

Two dimensional array

3 Common functions arange,linspace

linspace From beginning to end num Number , And the linear average cutting

4 section , restructure , Transposition

Take out the first two lines

Take out 1,2 Column

reshape
take 3 That's ok 3 Column , convert to 1 That's ok 9 Column


Transposition
