How to preallocate an array of class in MATLAB?

Question

I have an array of objects in MATLAB and I\'ve called their constructors in a loop:

antsNumber  = 5;
for counter = 1: antsNumber
    ant(counter) = TAnt(sour         


        

Answer 1

Not sure if I got your problem right, but if you want to initialize an array of your self-defined class "TAnt", here is how I would do it

1. For TAnt's constructor method, put something like:

function obj = TAnt(source, target)
         if nargin > 0
              obj.mySource = source;
              obj.myTarget = target;
         else
              obj.mySource = defaultValue;
              obj.myTarget = defaultValue;
         end
    end

Then to initialize/pre allocate an array of default TAnt objects,

ants(1,n) =  TAnt();  % n is the length of your ants array
