Introduction to MATLAB Data Types


MATLAB supports various data types for storing and manipulating data. In this guide, we'll introduce you to the most common data types in MATLAB and show you how to work with them.

Numeric Data Types

MATLAB primarily deals with numeric data. Here are some common numeric data types:

  • Double: MATLAB's default data type for real numbers. Example:
    x = 5.0; % Double
  • Single: Used for single-precision floating-point numbers, which consume less memory but have reduced precision. Example:
    y = single(3.14); % Single
  • Integer: Integers are whole numbers. MATLAB supports different integer types, such as int8, int16, int32, and int64.
    z = int32(42); % 32-bit integer

Character Data Type

MATLAB also supports character data:

name = 'John Doe'; % Character

Logical Data Type

MATLAB uses the logical data type for boolean values (true or false):

flag = true; % Logical

Cell Arrays

Cell arrays allow you to store data of different types and sizes:

cellArray = {'John', 42, true};

Working with Data Types

You can perform operations on data types, convert between them, and use built-in functions for various operations.

% Perform numeric operations
a = 5;
b = 3;
result = a + b;
% Convert data types
num = 5.67;
intNum = int32(num); % Convert to int32
% Use built-in functions
strLen = length('Hello, World!'); % String length


This guide has provided you with an introduction to the most common data types in MATLAB and how to work with them. As you continue to explore MATLAB, you'll discover more advanced data types and operations that will help you analyze and manipulate data effectively.
