eval(,) ... Up to my understanding, at this point
of using Smath for last 6 months it did 3 things
spread over ~ 200 Smath work sheets:

1. It recasts the Cholesky solver as a function
2. In program running for discretised data it
speeds up calculations [assuming it shortens the stack].
3. In the attached work sheet, it "manages" a form of
local definition, which Smath does not have Mathcad equivalent.

For visitors familiar with Mathcad/Mathsoft, observe carefully
the code translation.
Y<-- Y+K*sin(2*pi*X)
X<-- X+Y
they both "encapsulate" the RHS as new variable from <-- local def'n.
The Smath equivalent doing: eval(,) ...
Welcome if you have more descriptive explanation.

This work sheet about deterministic cahos is under construction.

That's the explanation of the author, hope it may helps: http://en.smath.info/forum/yaf_postsm1030_Samples-Nyquist-plot.aspx#post1030

Thanks Davide,

I was just correct, in my own words from observation.
