What happens when we want to program reasonably similar tasks for **hundreds** of different lines of **data**? Are we going to write a program with **900 lines of code**? **No!** We'll use **for loops**!

By translating our tasks into **for loops**, we can have a few lines of **code** execute **billions of tasks**. And when combined with **if statements** (next chapter), we can really start to **analyze data** in **complex** and **efficient** ways.  
Here we'll dip our toes in by learning the general behavior and **logical errors** that can arise. The **syntax** isn't super complicated, so you can start off with the set of **snippets** until you have it down, and in the next section we'll start using **for loops** to **analyze data** in **real world applications**.

### Task

Write a program with a nested for loop that:
- Creates a blank matrix;
- Assigns entry (i, j) of the blank matrix to i
  <super style="vertical-align: super; font-size: smaller">(j-1)</super> for 1 ≤ i ≤ 7 and 1 ≤ j ≤ 7.

Matlab's simplicity, efficiency, and overall computing power make it an excellent programming language for both beginners and top professionals alike. It's the language of choice for anything to do with numbers and data. This is an accelerated course designed to rocket you from beginner to professional, showing you every step along the way, so that you'll walk away ready to begin your programming career. 

Master Matlab's core syntax and coding techniques to create professional-grade programs. Explore essential functions, harness its power for data analysis, modeling, and engineering, and elevate your skills with hands-on exercises and real-world applications that accelerate your learning journey.

Master the foundations of data manipulation in Matlab, including importing data, utilizing for loops, and implementing if statements. Enhance your programming efficiency by modularizing your code, streamlining workflows, and building a solid foundation for advanced Matlab projects.

You'll apply everything you've learned to three real world situations and learn a whole bunch of syntax and details that come up in practice so that you can pull out concrete results from your Matlab programs.  

You'll start by getting your hands dirty exploring Matlab's top-tier visualization and graphing capabilities. After that, you'll learn how to automate graphing and combine the skills you already have to create custom visualizations. And on the way, you'll learn another fundamental aspect of programming: while loops.


To close out, this section will begin by teaching you about recursive programming and how it can help you automate analyses and graphing on a whole new level. After that, you'll dive into the world of matrix multiplication, where you can take advantage of Matlab's state-of-the-art algorithms to open a huge diversity of doors for your programming future.
