In this video, we move from 1D arrays to 2D arrays (matrices) in NumPy — one of the most important structures in data science, machine learning, and scientific computing.
Understanding 2D arrays is essential because most real-world data is organized in rows and columns. In this lesson, we break everything down step by step so you can confidently work with matrices in NumPy.
In this video, you’ll learn:
• How to create 2D arrays in NumPy
• The structure of rows and columns
• Accessing elements using row & column indexing
• Slicing 2D arrays
• Shape, dimensions, and reshaping basics
• Performing operations on matrices
By the end of this lesson, you’ll clearly understand how NumPy handles matrix-style data and how to manipulate it efficiently.
