vector_list = [1, 3, 5, 7, 9] # assuming this is the given vector list
target_value = 6
closest_value = min(vector_list, key=lambda x: abs(x - target_value))
print("the_closest_value_is:", closest_value)
In Python, I can use code to find the closest value. Is there a similar function available in DolphinDB?
