Basic Operations

% Arithmetic operations
x = 5 + 3;
y = 10 / 2;
z = 2^3;

% Matrix operations
A = [1 2; 3 4];
B = A’;
C = A * B;

Common Data Types

MATLAB supports multiple data types including:

  • Numeric (double, int32)
  • Logical (true/false)
  • Character arrays
  • Strings
  • Cell arrays
  • Structures
  • Tables
  • Timetables

Programming Fundamentals

Conditional Statements

if x > 0
disp(‘Positive’);
elseif x < 0
disp(‘Negative’);
else
disp(‘Zero’);
end

Loops

for i = 1:5
disp(i);
end

while x < 10
x = x + 1;
end

Creating Functions

function [output1, output2] = myFunction(input1,input2)

output1 = input1 + input2;

output2 = input1 * input2;

end

File Handling

save(‘data.mat’,’variable1′)

load(‘data.mat’)

data = readtable(‘data.csv’);

writetable(data,’output.csv’);

Data Visualization in MATLAB

Visualization is one of MATLAB’s strongest capabilities.

2D Plot

x = 0:0.1:2*pi;

y = sin(x);

plot(x,y)

title(‘Sine Wave’)

xlabel(‘X’)

ylabel(‘Y’)

grid on

3D Surface Plot

[X,Y] = meshgrid(-2:.2:2);

Z = X.*exp(-X.^2-Y.^2);

surf(X,Y,Z)

Multiple Graphs

subplot(2,1,1)

plot(x,sin(x))

subplot(2,1,2)

plot(x,cos(x))

Specialized Applications of MATLAB

Example:

 
syms x

diff(x^2)

int(x^2)
 

Image Processing

MATLAB simplifies image enhancement and computer vision.

Example:

 
I = imread('image.jpg');

Igray = rgb2gray(I);

imshow(Igray)
 

Applications include:

  • Face Recognition
  • Object Detection
  • Medical Imaging
  • OCR
  • Surveillance

Machine Learning

MATLAB supports:

  • Classification

Example:

 
model = fitctree(data,'Label');

predict(model,newData)

MATLAB Performance Optimization

Efficient coding improves execution speed.

Vectorization

Instead of loops:

 
for i=1:1000
y(i)=sin(i/100);
end
 

Use:

 
x=1:1000;

y=sin(x/100);
 

Vectorized code is significantly faster.

Memory Management

Best practices include:

  • Preallocate arrays using zeros()
  • Clear unused variables
  • Avoid dynamically increasing array sizes

Parallel Computing

MATLAB supports multicore processors.

 
parfor i=1:100

results(i)=heavyComputation(i);

end
