Aim:
To know and understand the basic 2D and 3D plotting commands in Matlab tool.
Softwares Required:
Matlab R2015a
Hardware Required:
A personnel Computer.
Procedures:
1. Open matlab File.2. Type the program in the editor window.3. Save the file with .m Extension and run the program.4. Verify the output in the command Window.
Theory:For 2-D graphics, the basic command is:
plot(x1, y1, 'line style', x2, y2, 'line style'...)
This command plots vector x1 versus vector y1, vector x2 versus vector y2, etc. on the same
graph. Other commands for 2-D graphics are: polar, bar, stairs, loglog, semilogx, and semilogy.
For 3-D graphics, the most commonly used commands are:
plot3(x1, y1, z1, 'line style', x2, y2, z2, 'line style'...)
contour(x,y,Z)
mesh(x,y,Z), surf(x,y,Z)
The first statement is a three-dimensional analogue of plot() and plots lines and points in 3-D.
The second statement produces contour plots of the matrix Z using vectors x and y to control the
scaling on the x- and y- axes. For surface or mesh plots, you use the third statement where x, y
are vectors or matrices and Z is a matrix. Other commands available for 3-D graphics are:
pcolor, image, contour3, _ll3, cylinder, and sphere.
