Constants in MATLAB

Question

I\'ve come into ownership of a bunch of MATLAB code and have noticed a bunch of \"magic numbers\" scattered about the code. Typically, I like to make those constants in lan

Answer 1

My way of dealing with constants that I want to pass to other functions is to use a struct:

% Define constants
params.PI = 3.1416;
params.SQRT2 = 1.414;

% Call a function which needs one or more of the constants
myFunction( params ); 

It's not as clean as C header files, but it does the job and avoids MATLAB globals. If you wanted the constants all defined in a separate file (e.g., getConstants.m), that would also be easy:

params = getConstants();
