Numpy----np. Tile() function parsing

Numpy:np.tile() Function analysis

master np.tile() The syntax of the function
This function treats the input as a whole , Make a copy

1. One dimensional copy of the array

print("***********************")
import numpy as np
a = [2,4,6]
b = np.tile(a,3)
print(b)
print("***********************")

Will array a Look as a whole , Copy 3 Input after times

2. Perform two-dimensional operations on the array

print("***********************")
import numpy as np
a = [2,4,6]
b = np.tile(a,(2,2))
print(b)
print("***********************")

take a As a whole , become 2 That's ok 2 Array of columns copied to b, Printout obtained

3. Transpose the array

print("***********************")
import numpy as np
a = [2,4,6]
b = np.tile(a,(2,2)).T
print(b)
print("***********************")

4. Comprehensive application

print("***********************")
import numpy as np
a = [2,4,6]
b = np.tile(a,(2,2)).T + np.tile((5,10),(6,1))
print(b)
print("***********************")
