Can you perform a delayed set (:= in Mathematica) in Matlab?

Question

So, I\'ve recently converted from Mathematica to Matlab, and while Matlab has most of Mathematica\'s useful features, I can\'t figure out how to perform the equivalent of Ma

Answer 1

Actually your proposed solution doesn't work as expected:

y = 2;
x = @()(y);
y = 3;
x()

when you define the anonymous function, it create a closure and captures/copies the value of y at that moment (now it has its own copy of y). Then if you change the y on the outside, it would not affect the one created in the closure, thus in your example the last value would return 2 not 3

The only way I can think of is to encapsulate the variable in a closure and expose set/get methods (just like in OOP)

IMO, MATLAB and Mathematica have two very different languages, thus I would embrace the MATLAB-way and not try emulate features of other languages (that is usually not the best thing to do)
