**Curriculum Module**

_Created with R2024a. Compatible with R2024a and later releases._

# Information

This curriculum module contains interactive [MATLAB® live scripts](https://www.mathworks.com/products/matlab/live-editor.html) that teach fundamental concepts and basic terminology related to programming computers. This module focuses on concepts and practices related to working with data.

## Background

You can use these live scripts as demonstrations in lectures, class activities, or interactive assignments outside class. This module covers textual data, numerical data, memory, and data structures including, arrays, structs, tables, and more. Applications include sea surface temperature data and solar power generation data.

The instructions inside the live scripts will guide you through the exercises and activities. Get started with each live script by running it one section at a time. To stop running the script or a section midway (for example, when an animation is in progress), use the <img src="Images/EndIcon.png" width="19" alt="EndIcon.png"> Stop button in the **RUN** section of the **Live Editor** tab in the MATLAB Toolstrip.

## Contact Us

Contact the [MathWorks Educator Content Development Team](mailto:onlineteaching@mathworks.com) if you would like to request assistance, provide feedback, or if you have a question.

## Prerequisites

These scripts assume familiarity with MATLAB and general programming knowledge at the level covered in the [Fundamentals of Programming](https://www.mathworks.com/matlabcentral/fileexchange/103225-fundamentals-of-programming) interactive examples. You could also use [MATLAB Onramp](https://matlabacademy.mathworks.com/details/matlab-onramp/gettingstarted) as another resource to acquire familiarity with MATLAB.

## Getting Started
### Accessing the Module
### **On MATLAB Online:**

Use the [<img src="Images/OpenInMO.png" width="136" alt="OpenInMO.png">](https://matlab.mathworks.com/open/github/v1?repo=MathWorks-Teaching-Resources/Programming-Organizing-Data&project=OrganizingData.prj) link to download the module. You will be prompted to log in or create a MathWorks account. The project will be loaded, and you will see an app with several navigation options to get you started.

### **On Desktop:**

Download or clone this repository. Open MATLAB, navigate to the folder containing these scripts and double\-click on [OrganizingData.prj](https://matlab.mathworks.com/open/github/v1?repo=MathWorks-Teaching-Resources/Programming-Organizing-Data&project=OrganizingData.prj&file=README.mlx). It will add the appropriate files to your MATLAB path and open an app that asks you where you would like to start.

Ensure you have all the required products (listed below) installed. If you need to include a product, add it using the Add\-On Explorer. To install an add\-on, go to the **Home** tab and select <img src="Images/AddOnsIcon.png" width="16" alt="AddOnsIcon.png"> **Add-Ons** > **Get Add-Ons**.

This script investigates strings, character arrays, and numeric data types and discusses how they interact in MATLAB. Formatting strings, modifying and extracting substrings, and building composite strings that include the results of numerical calculations are all explored. |
