comment How to avoid writing $K$ loops?
isn't this just n=3; a = Table[f[x1, x2, x3], {x1, n}, {x2, n}, {x3, n}] ?

comment Error when putting ??symbol in a cell with another expression
Some parsing confusion on the FE? One can clearly see this since ??NDSolve followed by 1+2 on new line gives Information[NDsolve 1 + 2, LongForm -> True] but this does not show up with the short form (default) version of Information which is ?

comment Error when using FullForm with ?symbol
my guess: Because you can't simply pass ? x as argument to a function, since ?x is not a symbol. i.e one can't make a symbol called "?" But The front end FE on the other hand simply parses this for you (it is being nice) and then converts internally to Information[x] and that is why it works now as argument to FullForm but you can't pass "? x" yourself as argument. It is meant to be used just for asking help on the FE only. I mean, only FE can parse this as first token read. Again, only a guess.

comment Error using Solve on Matrix Multiplication
@user9053 it is using least squares solution. We are using random numbers. But you have above Ax=b and xA=B definitions that I know about. Well, this is the limit of my linear algebra skills. If I think of something else will add.

comment How do I put a Monitor into CDF?
I do not have a database, but if an operation is blocking, I do not see how a progress bar will update during this time, unless you have a separate scheduled task running on the side. If you can a MWE that does not require database, that shows the problem, I am sure that will help understand more the issue.

comment Manipulate store values
If you can explain more. Do you mean you can to change x using a slider and have all the function values stored in a list for each x value changed. Then you want to click on a button to see the collected list?

sure, I did not look at times, just wanted to bring your attention that there is an answer there that might be what you wanted.

I thought there is answer for the above here mathematica.stackexchange.com/questions/30459/… (by @Jens). May be I overlooking something in the details...

comment How can this type of optical illusion be created in Mathematica?
is it my eyes or do I see it spinning? This only happens when I am not looking at it directly. I bet that either The Mathematica Guidebook: Graphics or Graphica: The World Of Mathematica Graphics both by Graphics Michael Trott will have something like this !

comment How do I use a while-loop to find the gain of a transfer function's limit?
There are easier ways to do this, but I am now confused about your TransferFunction. This can't be an actual transfer function. closed loop basic TF is $\frac{k H(s)}{1+ k H(s)}$ and what you do next is use RootLocusPlot to see where it crosses the $s$ axis for specific $k$. It is easy now to make a manipulate which varies $k$ and see which values causes it to become unstable.
