Hi, I want to know if Is there a dedicated function in NumPy for calculating the cube of an entire vector, similar to “np.square()” for squaring. Please provide code snippets.

Yes, there is a method to calculate the cube of a vector. The following code example uses the ** operator to cube each element of a vector:
In this example, a Numpy array is created using NumPy’s np.array method. The ** operator is then used to raise each element of the vector to the power of 3, which effectively cubes all the elements.
I hope this helps.
Another way to find the cube of a vector is using the Numpy np.multiply() method. The code snippet below describes the logic.
It creates a NumPy array “Z” and raises each element of “Z” to the power of 3 using the multiply() function, which is equivalent to using the ** operator. Finally, it stores the result in a new array “Z_cubed” and prints out the first five elements of this array.
Note that this method involves two calls to the multiply function and may be slower for very large vectors.
