Cumulative product refers to the process of incrementally multiplying the elements.
For instance, the partial product of [1, 2, 3, 4] is [1, 1*2, 1*2*3, 1*2*3*4] = [1, 2, 6, 24].
You can perform the cumulative product using the cumprod() function.
Calculate the cumulative product of all elements in the following array:
| import numpy as np arr = np.array([5, 6, 7, 8]) newarr = np.cumprod(arr) print(newarr) |
|
Returns: [5 30 210 1680] |
