Thread Subject: Matlab Architecture Question - Creating Modules in Matlab

I am interested in hearing ideas about the best ways to create "modules" in matlab?

The goal is to have one interface, where I can easily switch routines, and have different versions of the routine run.

For example, suppose I have a routine to recognize license plates. It needs to be initialized, and then on subsequent calls it needs to be run.

Later one, I want to swap the license plate recognition file, with another one, and have the new one take effect.

Is there an established 'best practice' for this in Matlab?

Hi "Pat",

One way to do this would be to manipulate the MATLAB path -- removing
the directory with the old routine and adding the directory with the new
one.

You could also do it with function handles:

  function_to_use = @function1;

  y1 = function_to_use(x);

  function_to_use = @function2;

  y2 = function_to_use(x);

but with this you have to give the two functions different names since
they will both be on the path at the same time.
