It discusses MATLAB's interface and use as a programming language, along with key features like arrays, basic operations, built-in functions, loops and conditions, graphics, images, and how to access MATLAB help. The overall focus is on introducing the basic concepts and capabilities of the MATLAB programming environment and language.
Introduction
Plotting basic 2-D plots.
The plot command
The fplot command
Plotting multiple graphs in the same plot
Formatting plots
USING THE plot() COMMAND TO PLOT
MULTIPLE GRAPHS IN THE SAME PLOT
MATLAB PROGRAM TO PLOT VI CHARACTERISTICS OF A DIODE
SUMMARY
How to 2D plots in Matlab. Easy steps to graph mathematical functions.
You have to define your interval of interest and consider a step in your independent vector, then you have to define your function and use an appropriate 2D built-in function.
More information and examples:

This is the slides of the UCLA School of Engineering Matlab workshop on Matlab graphics.
Learning Matlab graphics by examples:
- In 2 hours, you will be able to create publication-quality plots.
- Starts from the basic 2D line plots to more advanced 3D plots.
- You will also learn some advanced topics like fine-tuning the appearance of your figure and the concept of handles.

In MATLAB, a vector is created by assigning the elements of the vector to a variable. This can be done in several ways depending on the source of the information.
—Enter an explicit list of elements
—Load matrices from external data files
—Using built-in functions
—Using own functions in M-files
Octave - Prototyping Machine Learning AlgorithmsCraig Trim
Octave is a high-level language suitable for prototyping learning algorithms.
Octave is primarily intended for numerical computations and provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The syntax is matrix-based and provides various functions for matrix operations. This tool has been in active development for over 20 years.

The name MATLAB stands for MATrix LABoratory.MATLAB is a high-performance language for technical computing.
It integrates computation, visualization, and programming environment. Furthermore, MATLAB is a modern programming language environment: it has sophisticated data structures, contains built-in editing and debugging tools, and supports object-oriented programming.
These factor make MATLAB an excellent tool for teaching and research.
2. Outline
What is MATLAB.
MATLAB Interface
MATLAB as programming language.
Arrays in MATLAB.
Basic operations.
Some Built-in functions.
Loops and Conditions.
Graphics in MATLAB.
Image in MATLAB
MATLAB Help
3. What is MATLAB
High –level, data structured, technical computing
programming language.
Stands for Matrix Laboratory.
The basic data type is the Array (every thing is a matrix)
Scale n=1 is 1 x 1 array.
Vector a = [1 2 3] is 1 x 3 array (1-Dim).
Matrix A = [1 2 3 ; 4 5 6] is 2 x 3 array (2-Dim).
Used in linear algebra, graphic, image, simulation,.. Etc
5. MATLAB Interface
Menu bar.
Tool bar.
Command window.
Command History.
Current directory.
Workspace.
6. MATLAB as programming language
Like any other programming language MATLAB
contains variables , functions , loops , conditions ,,,
And so on.
As any other programming language , MATLAB can call
function of another language , and Also MATLAB ’s
functions can be called by any language.
7. Arrays in MATLAB
>> A = [1 2 3]
output is A = 1 2 3
>> A = [1 2 3];
output is null
( ; ) means execute without displaying output
8. Arrays in MATLAB
Matrix is 2-D array.
Vector is special case of matrix
-Vertical vector is m x 1 matrix - Horizontal vector is 1 x n matrix
>> A = [1; 2; 3] A= 1 >> A = [1 2 3] A = 1 2 3
2
3
Scale number is special case of vector
-scale is 1 x 1 vector
>>B = 5
9. Basic operations
^: exponentiation
*: multiplication
/: division
: left division. The operation AB is effectively the same as
INV(A)*B, although left division is calculated differently and is
much quicker.
+: addition
-: subtraction
11. Some Built-in functions
rand (m,n) magic (m)
mean (A) median (A)
min (A) max (A)
sum (A) sort (A)
dot (a,b) cross (a,b)
inv (A) length (A)
disp (A) load (A)

>>for i = 1:2 >> for I = 5:-2:1, I, end
i
end
Output Output
I=1 I=5
I=2 I=3
I=3 I=1
13. Loops and Conditions
>> n=3; >>n=0;
while n > 0 done = 0;
n=n-1 while ~done
end n = n+1
if n >= 3, done = 1; end
end
Output Output
n= 2 n= 1
n= 1 n= 2
n= 0 n= 3
14. Loops and Conditions
>> n = 3;
if n > 0 output
disp('Positive value.')
elseif n < 0 Positive value
disp('Negative value.')
else
disp('Zero.')
end
15. Graphics in MATLAB
As soon as graphs can represented by vectors, can be
manipulated by MATLAB like a normal vectors
>> x = [1 2 3 4];
>> y = [2 4 6 8];
>>title('Figure 1');
>>plot(x,y);
16. Image in MATLAB
As soon as images can represented by matrices, can be
manipulated by MATLAB like any other matrix.
>> x = imreade(' kids.tif ');
>>[x map] = imreade(' kids.tif ');
>>imshow(x);
>>imshow(x , map);
>>imwrite(x , ' c:img.png ' , 'png');
17. Image in MATLAB
To convert between different image types:-
x=imread(‘cameraman.png’);
Y=gray2rgb(x);
Y=rgb2gray(x);
Y=rgb2ind(x);
Y=ind2rgb(x);
Y=ind2gray(x);
Y=gray2ind(x);
18. Image in MATLAB
To rotate an image :-
X=imread(‘cameraman.png’);
y=imrotate(x,65,0);
degree of rotation
