String concatenation in MATLAB

Introduction

String concatenation lets you join two or more pieces of text into one longer text. This helps when you want to build messages or combine words.

Creating a full sentence from separate words or phrases.

Building file paths by joining folder names and file names.

Combining user input with fixed text to show messages.

Making labels or titles by joining different text parts.

Syntax

MATLAB

newString = [string1 string2 ... stringN];

Use square brackets [ ] to join strings in MATLAB.

Strings can be character arrays (using single quotes) or string objects (using double quotes).

Examples

Joins two character arrays into one: 'Hello, world!'

MATLAB

greeting = ['Hello, ' 'world!'];

Joins string objects to make a welcome message.

MATLAB

name = "Alice";
welcome = ["Welcome, " name "!"];

Concatenates two character arrays with a space included.

MATLAB

part1 = 'Good';
part2 = ' Morning';
full = [part1 part2];

Sample Program

This program joins 'Hello, ', the name 'Bob', and '!' into one string and shows it.

MATLAB

name = "Bob";
greeting = ["Hello, " name "!"];
disp(greeting);

Important Notes

When using character arrays (single quotes), make sure to include spaces if needed.

String objects (double quotes) are easier to work with for text operations in newer MATLAB versions.

Use disp() to display the concatenated string on the screen.

Summary

Use square brackets [ ] to join strings in MATLAB.

You can join character arrays or string objects.

Concatenation helps build messages or combine text parts.
