First, three examples are presented, as aids to help in understanding the Arrhenius equation and the diffusion problem:

 

The problem is solved using an MS Excel file, and charts are included.  

 

Instructions: save these programs in your Matlab work directory (hit the button with the ellipses (...) at the top of the Matlab window, in order to choose your work directory). Then write 'binomial' in the Matlab command window, and hit the 'enter' key... a plot (figure) with results should appear.

Main program: binomial.m -- this is the main program to execute from the command window

Auxiliary Matlab function:  factorial.m -- this is a small function that must be available in the same work directory where the main program 'binomial.m' has been saved.

 

The error function: a Matlab program to plot the error function, a cumulative probability.   

The program shows a solution to the problem of diffusion through an interface, at a given time after contact.

 

The error function: a Matlab program to generate a movie of how concentration changes with time.  

This program shows how the concentration changes with time, on both sides of a material interface
