How do I multiply a vector in Numpy?

Multiplying Vectors in NumPy: Let’s Make It Easy

NumPy, that amazing tool for number crunching in Python, gives you tons of ways to play with arrays, including vectors. Now, multiplying vectors might seem like a no-brainer, but NumPy actually has a few different tricks up its sleeve, each perfect for different jobs. So, let’s dive in and explore the various ways you can multiply vectors in NumPy, and I’ll show you when to use each one.

1. Element-wise Multiplication: Multiplying Side-by-Side

Think of element-wise multiplication – or the Hadamard product, if you want to get fancy – as lining up your vectors and multiplying each pair of numbers straight down the line. The result? A brand-new vector with the same shape, where each number is the product of the corresponding numbers from your original vectors. Simple, right?

How to do it:

• The * operator: This is your go-to for element-wise multiplication. It’s clean, it’s simple, it just works.
