This document discusses 2-D plotting in MATLAB. It introduces 2-D plotting and its uses, including for data analysis and visualization. It provides an example coding for plotting two functions simultaneously. The output shows the variation of quantities over time. Applications of 2-D plotting include building custom interfaces, improving code quality, and integrating algorithms with other languages and applications like Excel.

3. Introduction
MATLAB not only helps us for calculation but also
helps us in data analysis and visualization by plotting
graphs and waveforms. It provides us with a ‘big
picture’ of our data
Default 2d (‘plot’) and 3d (‘plot3’) plots in Matlab are
generally good. The only recommended change is to
avoid the legend (‘legend hide’). Replace this with
direct annotation.

4. Function
 When creating a MATLAB function, the name of the
file should match the name of the first function in the
file. Valid function names begin with an alphabetic
character, and can contain letters, numbers, or
underscores. Functions are also often case sensitive.
 Function handles
 MATLAB supports elements of lambda calculus by
introducing function handles, or function references,
which are implemented either in .m files or
anonymous/nested functions

5. Uses of 2-D ploting
 Apart from 2-D Plotting and graphics we use followings as
a combination according to our needs
 Linear Algebra
 Algebraic Equations
 Non-linear Functions
 Statistics
 Data Analysis
 Calculus and Differential Equations
 Numerical Calculations
 Integration
 Transforms
 Curve Fitting

6. 2-D ploting coding
Syntax :poly(x1,y1,x2,y2)
eg:
x=0:10;
y=x.^2;
z=2:12;
t=x.^2;
plot(x,y,z,t)

7. Output
Output of plot function of matlab ploting 2-D fuction at a time

8. EFFECT
 The graph is showing the variation quantity with
respect to time
 When we see at t=0 ,the quantity increases linearly
and when we set the t=2 then also it follows the same
pattern of increment.

9. Application
 It provides tools for building applications with custom
graphical interfaces
 MATLAB's programming interface gives development
tools for improving code quality, maintainability, and
maximizing performance
 It provides functions for integrating MATLAB based
algorithms with external applications and languages
such as C, Java, .NET and Microsoft Excel

10. conclusion
 To change the characteristics of the plot we can use
plottools function. A box will pop up showing your
output, we can change change the characteristics there
like color, plot type. We can also more data to the plot.
