softmax_function.py
# Softmax function
# SF(M) = e(A[i]) / sum(e(A))
# M: The given matrix
M = np.array([1, 2, 3])
# Calculate the exponential of all elements in the input array
M = np.exp(M)
# Calculate the ratio of the exponential of the parameter and the sum of exponential parameter
M = M / np.sum(M)
print(M)
