Academic Ally: MATLAB is a trusted companion in academia, simplifying teaching and research across various subjects.
Conclusion
My journey with MATLAB has been nothing short of transformative. Whether you're a student, researcher, engineer, or data scientist, MATLAB's array of features and toolbox collection can empower you to tackle complex problems and gain insights from data. Learning MATLAB has unlocked countless possibilities for innovation and discovery in my professional life. I encourage you to embark on your own MATLAB adventure and witness the incredible impact it can have on your projects and research endeavors.
I have given some snippets to understand MATLAB:
Arithmetic
a = 5;
b = 3;
sum = a + b;
difference = a - b;
product = a * b;
quotient = a / b;
Variables
name = 'John';
age = 30;
fprintf('My name is %s, and I am %d years old.\n', name, age);
Loop
name = 'John';
age = 30;
fprintf('My name is %s, and I am %d years old.\n', name, age);
x = 10;
if x > 5
disp('x is greater than 5');
else
disp('x is not greater than 5');
end
Adding to it we have some more complex codes:
System of linear equation
% Define the coefficient matrix A and the right-hand side vector b
A = [2, -1, 3; 1, 3, 2; 4, 2, 1];
b = [9; 12; 7];
% Solve for the unknowns x
x = A \ b;
disp('Solution for x:');
disp(x);
Numerical integration:
% Define the function to be integrated
f = @(x) sin(x) ./ x;
% Compute the definite integral from 0 to pi
result = quad(f, 0, pi);
disp('Integral result:');
disp(result);
3D plot:
% Define a grid of x and y values
[x, y] = meshgrid(-2:0.1:2, -2:0.1:2);
% Calculate the corresponding z values (example: a 3D surface)
z = x.^2 + y.^2;
% Create a 3D surface plot
surf(x, y, z);
xlabel('X-axis');
ylabel('Y-axis');
zlabel('Z-axis');
title('3D Surface Plot');
Image processing:
% Read an image
image = imread('sample_image.jpg');
% Convert to grayscale
gray_image = rgb2gray(image);
% Apply a Gaussian blur
blurred_image = imgaussfilt(gray_image, 2);
% Display original and processed images
subplot(1, 2, 1);
imshow(gray_image);
title('Original Image');
subplot(1, 2, 2);
imshow(blurred_image);
title('Blurred Image');
