comment Importing multiple files using a for-loop
@Probabilitnator Don't agree, I think help is very helpful in Mathematica. But one has to spend some time on it. ;)

Also, note that Table iterator doesn't need to be an increasing integer, but it can go over a list of files. Table[Import[file, "Data"], {file, files}].

comment Translating MATLAB's cell2mat into Mathematica
Yet couldn't we legitimize this question? Is the example in Mathematica {{{1}, {2, 3, 4}}, {{{5}, {9}}, {{6, 7, 8}, {10, 11, 12}}}}? How does one turn this into normal matrix?

comment How to plot a parametric region representing a coordinate transformation
What does t = infinity mean here? As I understand arctan(T/X) runs merely from -1 to 1, and so t from -Pi/4 to Pi/4 ... ?

comment Placeholders for map inside a map
But extracting one column doesn't need Map. Part[list1, All, 2] extracts 2nd column, and Map[Part[list1, All, #] &, {1, 3}] both 1st and 3rd.

comment Generating evenly spaced points on a curve
@Szabolcs I was asking. I think now that MeshFunctions -> (#4&) samples points with a constant step for parameter, which don't make the desired arcs.
