MATLAB is a proprietary multi-paradigm programming language and numeric computing environment developed by MathWorks. MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages. It is commonly used in engineering and scientific applications and provides powerful tools for numerical computation.

MATLAB Keywords

Keywords in MATLAB have specific meanings and cannot be used to name variables or functions. The following is a list of MATLAB keywords:

end function if else elseif while for switch case otherwise try catch break continue return

MATLAB Operators

Operators in MATLAB perform various mathematical and logical operations. The following is a list of MATLAB operators:

+ - * / ^ == > < <= >= ~= & | && ||

Mathematical Functions

The following are some commonly used mathematical functions:

sin() cos() tan() exp() log() sqrt() abs() min() max() ceil() floor()

MATLAB Data Types

MATLAB supports various data types for different types of numerical and non-numerical data. Some common data types include:

double, single, int8, int16, int32, int64, uint8, uint16, uint32, uint64, char, logical, cell, struct

MATLAB String Methods

There are various methods available for manipulating strings in MATLAB:

strlength(), strcat(), str2num(), str2double(), str2mat(), strcmp(), strncmp(), strfind(), strrep(), strtrim(), upper(), lower()

MATLAB Array Methods

There are various methods available for manipulating arrays in MATLAB:

length(), size(), numel(), reshape(), repmat(), flip(), fliplr(), flipud(), circshift(), find(), sort()

MATLAB File Methods

MATLAB provides functions for file I/O operations:

load(), save(), fopen(), fclose(), fread(), fwrite(), fprintf(), fscanf(), dir(), delete()

MATLAB Object Methods

MATLAB supports object-oriented programming with classes and methods:

methods(), properties(), classdef(), constructor(), destructor()

MATLAB List Methods

MATLAB provides functions for working with lists:

unique(), intersect(), setdiff(), setxor(), ismember(), union(), sort(), min(), max()

MATLAB Functions

Functions are essential in MATLAB for modular programming. You can define your own functions using the function keyword:

function result = myFunction(arg1, arg2)
    % Function body
    result = arg1 + arg2;
