MATLAB is a high-level programming language and interactive environment for numerical computation, visualization, and data analysis. It is widely used in engineering, science, and finance for tasks such as image processing, signal analysis, and machine learning.
Variables in MATLAB are declared using the = or : operator. MATLAB supports dynamic typing, so you don’t need to specify the type of the variable.
name = 'John';
age = 30;
pi = 3.14;
Functions in MATLAB are declared using the function keyword followed by the function name and parameters. MATLAB supports anonymous functions, which are functions that do not have a name and can be assigned to variables and passed as arguments to other functions.
function greet(name)
fprintf('Hello, %s!\n', name);
end
greet('John');
add = @(a, b) a + b;
disp(add(2, 3));
MATLAB supports for and while loops, as well as the if, else if, and else statements.
numbers = [1, 2, 3, 4, 5];
for number = numbers
disp(number);
end
i = 0;
while i < 5
disp(i);
i = i + 1;
end
MATLAB supports if, else if, and else statements, as well as the ternary operator.
age = 30;
if age < 18
disp('You are too young to vote.');
elseif age < 21
disp('You can vote, but not drink.');
else
disp('You can vote and drink.');
end
result = age >= 18 ? 'You are an adult' : 'You are not an adult';
disp(result);
MATLAB provides several ways to read and write files. You can use the fopen, fprintf, fscanf, and fclose functions to create, read, write, and delete files.
file = fopen('example.txt', 'w');
fprintf(file, 'Hello, world!');
fclose(file);
file = fopen('example.txt', 'r');
content = fscanf(file, '%c');
disp(content);
fclose(file);
delete('example.txt');
