Compute cumulative product of elements using np.multiply.accumulate
NumPy: Universal Functions Exercise-10 with Solution
ufunc Accumulate Method:
Write a NumPy program that uses the np.multiply.accumulate ufunc to compute the cumulative product of elements in a 1D array.
Sample Solution:
Python Code:
import numpy as np
# Create a 1D NumPy array of integers
array_1d = np.array([1, 2, 3, 4, 5])
# Use the np.multiply.accumulate ufunc to compute the cumulative product of elements in the array
cumulative_product = np.multiply.accumulate(array_1d)
# Print the original array and the cumulative product of its elements
print('Original 1D array:', array_1d)
print('Cumulative product using np.multiply.accumulate:', cumulative_product)
Output:
Original 1D array: [1 2 3 4 5] Cumulative product using np.multiply.accumulate: [ 1 2 6 24 120]
Explanation:
- Import Libraries:
- Imported numpy as "np" for array creation and manipulation.
- Create 1D NumPy Array:
- Create a 1D NumPy array named array_1d with integers [1, 2, 3, 4, 5].
- Use np.multiply.accumulate ufunc:
- Used the np.multiply.accumulate ufunc to compute the cumulative product of elements in the array_1d. The accumulate method applies the np.multiply ufunc cumulatively to the elements of the array, resulting in the cumulative product.
- Print Results:
- Print the original array and the cumulative product of its elements computed using "np.multiply.accumulate".
