Matlab Example Programs and Utilities

Sort by: Name | Most recent

ascii_art.m
ASCII art example

base_conversion.m
Convert a number from one base to another
Supports decimals, bases up to 36, only positive numbers

better_menu_example.m
Better menu example
A simple alternative to MATLAB's menu command - centered and optional sizing

bounce.m
Bouncing ball game
A good example of animation and real-time user interaction

cell_extract.m

center_mass_image.m
Compute the center of mass of an image
by treating each pixel as a point mass

center_menu.m
Purpose: Create a centered MATLAB menu
Method: Create a timer that moves the menu after it is displayed
because MATLAB doesn't provide a way of positioning the menu.
This is kludgy, but it seems to work.

coulomb.m
Electric forces in a system of particles - Coulomb's Law

create_animation.m
Example of creating a movie (avi) file from a series of plots

curvature.m
Demonstrate symbolic math in MATLAB
Calculate the radius of curvature for trajectory equation
Calculate normal and tangential acceleration components

dictionary_read.m
Example of reading a ~500,000 word dictionary into Matlab
This example loads all words into a cell array and keeps a track of
the count of the lengths and displays all words over 20 characters long

digitize.m
Example of reading an image, rotating it, and digitizing data from it.

ef_shooter_gui.m
Engage golf ball gun analysis/simulator
A GUI for setting parameters and displaying results of a 'shooter'

file_text_table.m
Example of creating a text file with a table of data

gpa2.m
GPA calculator example
reads and writes text data files

image_cropper.m
Interactive image cropping
Prompts user for a file name of a file that contains one or more
images that are to be rotated and cropped. The user then clicks on the
corners of the images and Matlab extracts, rotates, crops, and
saves the sub-image(s).
