Ayirmalar

Diskret ayirma ketma-ket kelgan ikki elementni bir-biridan ayirishni anglatadi.

Masalan, [1, 2, 3, 4] uchun diskret ayirma [2-1, 3-2, 4-3] = [1, 1, 1] bo‘ladi

Diskret ayirmani topish uchun diff() funksiyasidan foydalaning.

Misol

Quyidagi massivning diskret ayirmasini hisoblang:

import numpy as np arr = np.array([10, 15, 25, 5]) newarr = np.diff(arr) print(newarr)

O‘zingiz sinab ko‘ring »

Natija: [5 10 -20], chunki 15-10=5, 25-15=10 va 5-25=-20

n parametrini berib, bu amalni takroran bajarishimiz mumkin.

Masalan, [1, 2, 3, 4] uchun n = 2 bo‘lganda diskret ayirma avval [2-1, 3-2, 4-3] = [1, 1, 1] bo‘ladi, so‘ngra n=2 bo‘lgani uchun bu amalni yangi natija bilan yana bir marta bajaramiz: [1-1, 1-1] = [0, 0]

Misol

Quyidagi massivning diskret ayirmasini ikki marta hisoblang:

import numpy as np arr = np.array([10, 15, 25, 5]) newarr = np.diff(arr, n=2) print(newarr)

O‘zingiz sinab ko‘ring »

Natija: [5 -30], chunki: 15-10=5, 25-15=10 va 5-25=-20, HAMDA 10-5=5 va -20-10=-30
