File Exchange Pick of the Week

August 20th, 2008

We have MATLAB users come into The MathWorks to present their work in MATLAB from time to time. Recently there was an interesting presentation with some really great “Clutter classification” algorithms in a GUI. One of the questions that came out of that discussion was how to get rid of a bunch of EVAL statements from their code. The following code shows how they can be avoided using “dot parens notation”, or Dynamic Field Names as they are formally known.

a.doug = ‘Hull’
a.jiro = ‘Doke’

name = ‘doug’;

last = a.doug
eval(['last = a.' name]) %BAD
last = a.(name) %GOOD

Doug first used MATLAB in 1994, could not figure it out until he got some help in 1995. He is now dedicated to making sure that no one else wastes a year of their life not knowing MATLAB like he did.
