Parameters :
array: [array_like] Input array. repetitions: No. of repetitions of arr along each axis.
Return:
An array with repetitions of array - arr as per d, number of times we want to repeat arr
Code 1:
| # Python program illustrating
# numpy.tile () import numpy as geek
# Working on 1D arr = geek.arange ( 5 ) print ( "arr:" , arr) repetitions = 2 print ( "Repeating arr 2 times:" , geek.tile (arr , repetitions)) repetitions = 3 print ( " Repeating arr 3 times: " , geek.tile (arr, repetitions)) # [0 1 2 ..., 2 3 4] means [0 1 2 3 4 0 1 2 3 4 0 1 2 3 4]
# since this was long output, so it uses [...] |
Output:
arr: [0 1 2 3 4] Repeating arr 2 times: [0 1 2 3 4 0 1 2 3 4] Repeating arr 3 times: [0 1 2 ..., 2 3 4]
Code 2:
| # Python program illustrating
# numpy .tile () import numpy as geek arr = geek.arange ( 3 ) print ( " arr: " , arr) a = 2 b = 2 repetitio ns = (a, b) print ( "Repeating arr:" , geek.tile (arr, repetitions)) print ( "arr Shape: " , geek.tile (arr, repetitions) .shape) a = 3 b = 2 repetitions = (a, b) print ( "Repeating arr:" , geek.tile (arr, repetitions)) print ( "arr Shape:" , geek.tile (arr, repetitions) .shape) a = 2 b = 3 repetitions = (a, b) print ( "Repeating arr:" , geek.tile (arr, repetitions)) print ( "arr Shape:" , geek.tile (arr , repetitions) .shape) |
Output:
arr: [0 1 2] Repeating arr: [[0 1 2 0 1 2] [0 1 2 0 1 2]] arr Shape: (2, 6) Repeating ar r: [[0 1 2 0 1 2] [0 1 2 0 1 2] [0 1 2 0 1 2]] arr Shape: (3, 6) Repeating arr: [[0 1 2 ..., 0 1 2] [0 1 2 ..., 0 1 2]] arr Shape: (2, 9)
Code 3: (repetitions == arr.ndim) == 0
| # Python program illustrating
# numpy.tile () import numpy as geek arr = geek.arange ( 4 ). reshape ( 2 , 2 ) print ( "arr:" , arr) a = 2 b = 1 repetitions = (a, b) print ( "Repeating arr:" , geek.tile (arr, repetitions)) print ( "arr Shape:" , geek.tile (arr, repetitions) .shape) a = 3 b = 2 re petitions = (a, b) print ( "Repeating arr:" , geek.tile (arr, repetitions)) print ( "arr Shape: " , geek.tile (arr, repetitions) .shape) a = 2 b = 3 repetitions = (a, b) print ( "Repeating arr:" , geek.tile (arr, repetitions)) print < code class = "plain"> ( "arr Shape:" , geek.tile (arr, repetitions) .shape) |
Output:
arr: [[0 1] [2 3]] Repeating arr: [[0 1] [2 3] [0 1] [2 3]] arr Shape: (4, 2) Repeating arr: [[0 1 0 1] [2 3 2 3] [0 1 0 1] [2 3 2 3] [0 1 0 1] [2 3 2 3]] arr Shape: (6, 4) Repeating arr: [[0 1 0 1 0 1] [2 3 2 3 2 3] [0 1 0 1 0 1] [2 3 2 3 2 3]] arr Shape: (4, 6)
