Web3 sep. 2024 · C = A – B subtracts array B from array A by subtracting corresponding elements. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other. For example, if A or B is a scalar, then the scalar is combined with each element of the other array. WebWe can also use the add operator “+” to perform addition of two arrays. import numpy as np a = np.array([10,20,100,200,500]) b = np.array([3,4,5,6,7]) print(a+b) Output [ 13 24 105 206 507] NumPy Subtract function.
