comment GatherBy and two conditions
You can gather into nested sublists using GatherBy[list, {#[[3]] == 6 &, Last}]

comment For loop in Mathematica
I fixed your code using Halirutan's awesome browser script. Generally it is simpler just to avoid using Greek letters in code you post here.

comment How to fill a whole rectangle with text?
Looks like a bug to me. I used StringTake[ExampleData[...], n] and varied n with a Manipulate. For some string lengths the font is magnified as expected, for others it isn't.

comment Re-arranging / selecting of a data table very slow in For loop
It's slightly quicker, at least on my PC with this data, to just use Mean /@ GatherBy[test, First]

comment Plot Matlab icon
@xzczd, LaplacianFilter implements the Discrete Laplace Operator with a convolution. The second argument of LaplacianFilter just determines the size of the convolution kernel. By setting this to 1 the smallest possible kernel is used (3x3) which keeps lapMatrix as sparse as possible. If you use a larger kernel you will get a bit more accuracy but slow down the eigenvector calculation.
