comment How to define a vector with automatically added symbolic elements with subscripts
Have you thought about what should happen if you define $k_1$ and $k_3$, but not $k_2$? Does the resulting list only contain $\{k_1, k_3\}$ or is there supposed to be some placeholder for $k_2$? Can't really answer your question if that isn't defined first.

comment Define new number set
@Mr.Wizard Fascinating what people have done with the game of life. My kids and I spent some time exploring Golly (the program linked in the article) many years ago...

comment How can I factor my trigonometric equation?
I don't think your answer is wrong. It's the question that's inaccurate. The stated factor isn't really a factor, in the sense that one can't convert the equation to a polynomial such that the variable $z = \cos x-1$ is a factor. And your answer shows this, I think. I edited your answer to format the code.

My understanding was that the data aren't necessarily given by a known function...

comment Fitting data without an equation
The simplest fit is linear interpolation between data points. And that is done by using the following magical incantation: ListPlot[H, Joined -> True]. Do you want anything fancier that this? If so, could you describe it in more detail?

You probably forgot to copy the line SetAttributes[myList, HoldAll]

I didn't get what your goal was initially, but I think now the DumpSave should work.

comment Sum and NSum gives different solutions
@whuber One should however be careful not to overstate the differences between Sum and NSum. According to the documentation for Sum (under "Properties"): Applying N to an unevaluated sum effectively uses NSum

comment how to generate functions with changing array size?
Right, I overlooked the lower bound. It's corrected now. Also, I think I added what you meant in terms of the f[i,x], but I'm not sure if you wanted them to remain symbolic or see their values as it appears in my answer.
