comment Custom plot range cropping
This looks what I was looking for. I'm not sure about the labeling but I think I can work with it. Thank you!

comment Custom plot range cropping
Well, ok, this is a solution i was aware of as well. The point is that this method is like the last resort (at least in my case). I believe that the picture is not as clear as stacked plots.

comment Replacing elements of a nested list by some value
You can start with list[[1,;;]]=20. It should be easy to generalize this in the way you need it.

comment Manipulating list of matrices
If you want to deal with columns, just transpose your matrix using Transpose. This way the columns will turn into rows and the above method will work again. Note that you will need to transpose the matrix one more time after you finish your procedure.

Use Select[#,#1[[2]]>10^6&]&/@matrix. You can use Map to generalize it on the whole list.

comment Plot Epilog FindMaximum
This basically means {apply the rule from the last element of # to x, take the first element of #}, where # is an argument and & ends a definition of a function. @ works almost the same as [] so, for instance, Sin[x] is the same as Sin@x (but in general @ has different evaluation order, take a look on its documentation). Try to read sth about slots (#), maybe it will clear things out for you. reference.wolfram.com/language/ref/Slot.html

comment Applying N to the roots found by Solve gives complex numbers when the roots are real
Use Chop. It will cut off very small numbers. In yur case you'll be able to ged rid of the imaginary part.

comment How to solve time dependent Optical Bloch Equations for a three level system?
Please rewrite your question. Try to avoid Subsript functions and greek letters- > it will be much easier to read your code. Also, if there are 9 coupled differential equations, I would go with NDSolve.

comment A question regarding “DiscretizeGraphics”
There was an error with def. of tor function (R^2 instead of R). It's fixed now. The range of variables has been modified as well.
