b1 = < 1, 0 >

b2 = < 1, 2 >

c = < -2, 3 >

In [1]: b1=np.array([[1],[0]])

...: b2=np.array([[1],[2]])

...: c=np.array([[-2],[3]])

...: b=np.hstack([b1, b2])

In [2]: print(b)

[[1 1]

[0 2]]

In [3]: print(c)

[[-2]

[ 3]]

In [4]: r=np.dot(b, c)

...: print(r)

[[1]

[6]]

The above results can be seen in Fig. 5.1.

Fig. 5.1 Correction of coordinates by basis vectors.

As shown in Fig. 5.1, the result of Ex. 5.2, c can be represented by r in a coordinate system with base vectors b 1 and b 2 as reference coordinates.
