comment Specifying string patterns in a plain text
I think you have not allowed for some spaces in your pattern.

comment Manipulating form of output redux
It seems it this case, if you can live with it, if you make the change mu[1]->mu1,mu[2]->mu2 (etc) that changes to pecking order of the symbols enough that the order comes out the way I think you want.

comment Manipulating form of output redux
The remaining question can now be posed quite simply as how do we tell mathematica to order something of the form Conjugate[B] x[1] + B x[2] so that the B term is first. Unfortunately I think the answer is you will end up pulling all your hair out if you don't learn to live with the way mathematica wants to order things.

comment Keep leading/trailing zeroes (like Defer except with numbers) in a given number
you could mess around with $PreRead. It would be a lot of headache just to avoid typing quote marks around the numbers when you key them in though. (I actually think this is a dup, but I cant find it at the moment)

comment Mathematica script file in Linux - how to export PDF file and close kernel?
both work just fine for me with v10. (Quit[] is not needed ) running directly (i don't have at ). Its either a version issue or something peculiar about at.

comment Creating “detached” plots
cool, but you need to have it appear behind all my other windows for a true matlab-like experience. ("ThinFrame" makes a window you cant get rid of on windows too, btw )

comment Manipulating output of polynomial expansion
for the first part you need to do a Collect inside Exp inside the functionwhole definition. Work on that first, maybe the other problem will be taken care of as well.

comment Manipulating output of polynomial expansion
you know Collect is not operating at all on the expressions inside Exp..

I don't see Conjugate[B] + B in your example, nor do I think you will ever see that since it will always be put in canonical order B+Conjugate[B]

comment How to get the meaning of a Mathematica symbol you don't know ?
note a "symbol that I don't know" isn't necessarily a documented thing so F1 may not work.

comment Which values did ImageAdjust choose?
ImageAdjust actually does a linear transform, so properly you need to fit to a scale + offset form. (this will work if keyimage has at least one completely black pixel.. )

comment Odd plotting/math issue (could be a precision problem)
I suspect this requires more of a mathematics study of the function rather than relying on numerical evaluation even at high precision.

comment Odd plotting/math issue (could be a precision problem)
I believe it is a precision issue, try this to force high precision calculation: N[const[10, 1/100, 31/10]*f[2/1000, 10, 1/100, 31/10], 100] you will see the result is purely real .

comment Is tensor argument passing to module expensive?
most of your constants k,r,etc simply alternate values between odd/even iterations (Except on the first pass). This would be far more efficient if you precompute those values outside the loop ( ie. reven= .. , rodd = ). The fact that they are different only on the first pass make me wonder if your algorithm is really doing what you expect.

comment Which values did ImageAdjust choose?
I don't see where it says it is equivalent to Rescale, but it is clearly not true for multi channel images. For color images ImageAdjust works independently on each channel while Rescale applies a single transformation to the whole data array. Oddly ImageAdjust does not provide options to manually specify each channel range, so you cant use it directly even if you know the transform the auto setting used.

comment Error with ND Solve
I don't that error. I get a solution (two solutions actually) that stop around t=.29, which is indicating the issue is with your formulation, not with your mathematica code.
