Shared variable

Shared variable can create a alias or used as pass-by-reference argument.

This is a helper class which can be used to create a shared object. A shared object works like normal data types but can create a alias variable or use as pass-by-reference argument.

For example:
a = shared([1:10]);
b = a;
b(10) = 0; %% a(10) will get 0 too.
inplace_incr(b) %% a(1:10) will be increased too.

function inplace_incr(a)
a.data = a + 1;
end
