comment Graphics updating from inside double-Fold-iteration within Manipulate
It works, thanks! I also figured out the meaning of {{v, v}, ControlType -> None}: Because controls format are executed in advance to the Initialization options. So when firstly executing control, a undefined symbol v is asigned to the variable v; then while executing initialization, the symbol v is defined to be a function name, therefore the variable v now will be automatically recognized by the local master kernel as a function name.

@ Michael E2 This problem is clearly addressed in your second solution, which I appreciate better, because it offers more controls and freedom. But I am still curious to know if we can show both g and k in the Button solution :)

@Micheal E2 I just got a trival question: In your Button solution, the current value of k can not be shown even with {Dynamic[k], Dynamic[g]}, because the evaluation is done outside the main body. I wonder if we could show both k and g simultaneously?

I managed to come up with a possible solution, but this one may have efficiency issue. Hope someone can help to improve it.

Yes you are right. Actually me current code is just in the first form you provided. However I want to submit my FEM code to WolframDemonstrationProject, so I will have to convert it using Manipulate. Still, thanks for your second code, there is something new to me.

comment Automatically tracing and keeping ViewPoints in a list while manually rotating 3D graphics
Adopting Szabolcs's code, we can also write something like: vprec = {}; vvrec{}; then change the Dynamic[vp, (vp = #; vprec = list[vprec, #]) &] to Dynamic[vp, (vp = #; AppendTo[vprec, #]&]. This makes the code easier to read, but may decrease performance in complex situation.

Amazing! I will need to go deep into Dynamic... Thanks!

@Szabolcs: I just hope to do as many things as possible from within Mathematica :)

Add: I mean still using the compact way of expressing the equation.

comment NDSolve problem with matrix valued function
I have an additional question: Since σxy and σyx are identical, can we just tell Mathematica this and thus accelerate the calculation?

This is more closely related to my question. Thank you VLC!
