Question

the following are numpy arrays:

x = [1 0]

[0 1]

y = [1 2]

[3 4]

what numpy function would put both of these arrays in to the following 4x4 matrix:

p = [x x]

[y y]

so it would like this:

p = [1 0 1 0]

[0 1 0 1]

[1 2 1 2]

[3 4 3 4]

Answer 1

Here is the answer...

CODE:

import numpy as np
x = np.array([[1, 0],[0,1]])
y = np.array([[1, 2],[3,4]])
print(type(x))
print("X =",x)
print(type(y))
print("Y =",y)
p=np.column_stack([[x,x],[y,y]]) #here we arrange column wise

k=np.column_stack(p) #again arrange in column wise
m=np.asmatrix(k) #convert them to matrix
print("\nMatrix is")
print(m) #print matrix
print(m.shape,type(m)) #print its shape and type

CODE and OUTPUT:
