Making Structures Persistent

To make structures persist, you define them to be persistent variables and initialize them with the isempty statement, as described in Defining and Initializing Persistent Variables.

For example, the following function defines structure X to be persistent and initializes its fields a and b:

function f(u)  %#codegen
persistent X

if isempty(X)
   X.a = 1;
   X.b = 2;
end
