🖥️ MATLAB GUI Mini-Course
Welcome! This course walks you through creating GUIs in MATLAB step by step.
📘 Lesson 1: Creating a Window + Button

📝 A figure is your GUI window. uicontrol creates interactive elements.
📘 Lesson 2: Textboxes & Input
Output here...
⚡ Use get() to grab values from user input fields.
📘 Lesson 3: Multiple Controls & Layout
Output here...
👋 This shows multiple controls working together: labels, textboxes, and a button.
📘 Lesson 4: Callback Functions & Logic
Output here...
✅ Checkboxes return 1 if selected, 0 if not.
📘 How to Create a GUI (Using MATLAB GUI Editor)
MATLAB provides two main ways to design GUIs without writing all the code manually:
- GUIDE (Legacy) — The older GUI Design Environment (still available in many MATLAB versions)
- App Designer — The modern replacement for GUIDE (introduced in newer MATLAB versions)
🛠️ Using GUIDE
- Type
guide in the MATLAB Command Window.
- Select a blank GUI (or template).
- Drag & drop controls (buttons, sliders, text boxes) from the toolbox onto your window.
- Save the GUI — MATLAB will create two files:
myGUI.fig → the layout (UI)myGUI.m → the logic (callbacks and code)
- Double-click a control (like a button) to add custom code in its Callback function.
⚡ GUIDE is being phased out, but it’s still great for learning because it shows the link between GUI layout and MATLAB code.
🛠️ Using App Designer
- Type
appdesigner in the MATLAB Command Window.
- Drag & drop UI components from the Component Library (buttons, sliders, switches, etc.).
- Adjust properties in the right-hand panel (text, size, colors, callbacks).
- Add interactivity by writing code in the
Code View.
- Save your app as a
.mlapp file — this is a self-contained GUI app.
🚀 App Designer is the future. It uses an object-oriented approach and integrates better with modern MATLAB apps.
