comment using elements from a matrix into a function
you do not have nPlate defined, and you need a ";", not a "," inside your Do loop between the statements. You must have seen these errors when running the code? Mathematica will beep and generates error messages.

comment How to load a custom mathematica package from a .m file?
@daOnlyBG The image you show above !Mathematica graphics indicates you hit "=" before. Do not use the "=" to type the commands. This will send the commands to the Wolfram alpha server on the Wolfram Cloud. Just type SetDirectory[NotebookDirectory[]]; as is without hitting "=" before it. Make sure again you have saved the notebook to the same folder as the package. Do not use the Wolfram Cloud functionality.

comment RowReduce doesn't work for this matrix?
Row Reduced /= Gaussian elimination. The result returned is correct. May be you meant LUDecomposition[A] which gives {{1, 0, 1, x}, {0, 1, 1, w}, {-1, 0, 2, 1 + x}, {0, 1, 0, -w + z}} ? I do not know how you obtained {{1,0,0,1/2x-1/2y},{0,1,0, -1/2x-1/2y+w},{0,0,1,1/2x+1/2y},{0,0,0,w-z}}

comment Which Mathematica function has the longest name (by character length?)
@MichaelE2 I just did not have "CalculateUnitsUnitCommonSymbols" in my list of packages, since I could not find it on the installation disk. I just added it there. Will update now.

comment How to export LaTeX expressions with subscripts and greek letters?
Can I name variables using a backslash aswell? There is no need. Mathematica will add the backslash for you automatically when you export to Latex. Try TeXForm[Sin[x]] You'll see the result is \sin (x). I do not think a variable name can start with "\" in Mathematica. I just tried \x=5 in Mathematica, and it gave me syntax error. Version 10.01 on windows.

comment How to export LaTeX expressions with subscripts and greek letters?
what is the best way to integrate the use of mathematica and latex? There are 2 ways: Export as tex using the menu, or use TeXForm for an expression.

comment A question about conditional replacement
This has been answered before. It is the same as the difference between SameQ and Equal. Instead of repeating things, please see this difference-between-and-in-mathematica which talks about the difference between SameQ and Equal. This applies exactly to UnSameQ and Unequal.

comment MKL on Intel vs AMD
from Math_Kernel_Library Nevertheless, the 64-bit version of the Math Kernel Library has been criticized for being suboptimal on non-Intel processors There is a link above for additional information on this as well.

comment Inverse error function
From help for InverserErf it says Explicit numerical values are given only for real values of s between -1 and +1. But you have complex arguments.

comment Inverse error function
Can you show the Mathematica code? Because when I typed y = Exp[(Erf[I t]^(-1))^2]; Plot[y, {t, -1, 1}] I get this !Mathematica graphics

comment symbolic integration of product of hankel function and trignometric function
There is no closed form solution for Integrate[BesselJ[0, k r] Cos[r], r] which what causes this to fail. There is a analytical solution for k=1. k = 1; Integrate[r*Cos[r]*HankelH2[0, k*r], r] gives 1/4 (2 r^2 HypergeometricPFQ[{1/4, 3/4}, {1/2, 1/2, 2}, -r^2]- I Sqrt[2] MeijerG[{{1, 5/4, 7/4}, {1/2}}, {{1, 1}, {0, 1/2, 3/2, 3/2}}, r, 1/2]) might also be better to ask this on the math group.
