Details:
Calling
f=@(t)eval('t');f(3)
produces
error: 't' undefined
So you could think the string is evaluated on the assignment of f. This is
confirmed by the following:
t=3;f=@(t)eval('t');f(2)
Which returns 3.
But if you type following, you see that the statement above is not true:
clear t;f=@(t)eval(num2str(t));f(42)
which returns 42.
In Matlab, the string within eval is only evaluated when f is called,
consistently.
