*copy the file to your current directory. Example- If you want to find a root of f(x)=6x^3+8x^2-3x^1+78, write the command- find_root([78 -3 8 6]); on MATLAB command window. *If you want to find another root, change the 100 in, x=100; (4th line of find_root.m file) to another value as your preference and rerun find_root([78 -3 8 6]); command. *for further details about the algorithm used to calculate roots. refer http://en.wikipedia.org/wiki/Newton%27s_method

- Fourier Analysis of a Rectangular Pulse
- License: Freeware
- Price: 0.00


Finding the Fourier transform of a rectangular pulse.. filtering the spectrum and regenerating the signal using the filtered spectrum is done... at the end Rayleigh theorem is proved by showing that the energy content of both time domain and frequency domain signals are equal.. your comments are required.....

- image processing-zooming an image using Bilinear interpolation
- License: Shareware
- Price:


An image in your root directory can be zoomed by calling the above program. *First try with a small image. Because when the image is smaller, program response quickly. How to Run the Program *copy bilinear_zoom.m file and the image file to your work directory. Example- *if the name of image in root directory is image.jpg and the zooming factor you expect is 5. *run following code in command window. bilinear_zoom('image.jpg',5); *Use the enter key always, when the display does not show any change. *If you want to know the the algorithm used refer-: http://en.wikipedia.org/wiki/Bilinear_interpolation

- zooming an image using nearest neighbor interpolation
- License: Shareware
- Price:


zooming a given image by a given positive factor can be done.. copy nearest_neighbor_zoom.m file and the image file that should be zoomed to your work directory. if the name of the image file is image.jpg and the zooming factor needed is 2.23, run following command on command window. nearest_neighbor_zoom('image.jpg',2.23); Leave your comments...
