NumPy can compute the sum of numbers that are in the vicinity of a given number using the numpy.sum
function along with boolean indexing. Here is an example:
import numpy as np
# generate an array of random numbers
arr = np.random.rand(10)
# choose a central number
center = 0.5
# define the vicinity range
vicinity = 0.1
# boolean indexing to select numbers within the vicinity range
selected = (arr >= center - vicinity) & (arr <= center + vicinity)
# compute the sum of selected numbers
sum = np.sum(arr[selected])
print(sum)
In this example, we first generate an array arr
of 10 random numbers. We then choose a center
number and define a vicinity
range around it. We use boolean indexing to select the numbers in arr
that are within the vicinity
range of the center
number. Finally, we use the numpy.sum
function to compute the sum of the selected numbers.
