How to do it…

Let's look the the different methods.

Matrix addition

In order to understand how matrix addition is done, we will first initialize two arrays:

# Initializing an arrayx = np.array([[1, 1], [2, 2]])y = np.array([[10, 10], [20, 20]])

Similar to what we saw in a previous chapter, we initialize a 2 x 2 array by using the np.array function.

There are two methods by which we can add two arrays.

Method 1

A simple addition of the two arrays x and y can be performed as follows:

x+y

Note that x evaluates to:

[[1 1] [2 2]]

y evaluates to:

[[10 10] [20 20]]

The result of x+y would be equal to:

[[1+10 1+10] [2+20 2+20]]

Finally, this gets evaluated to:

[[11 11] [22 22]]

Method 2

The same preceding operation can also be performed by using ...
