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.

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 handlesMATLAB supports elements of lambda

calculus by introducing function handles, or function references, which are implemented either in .m files or anonymous/nested functions

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

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)

Output

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

EFFECTThe graph is showing the variation quantity

with respect to timeWhen 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.

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

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.
