Quote:Hi,Yea - that article was over my head too unless you are using Fourier transforms for "In military tactical formations, "linear formations" were adapted from phalanx-like formations of pike protected by handgunners towards shallow formations of handgunners protected by progressively fewer pikes. This kind of formation would get thinner until its extreme in the age of Wellington with the 'Thin Red Line'."
Linear in math means a lot more than a straight line relationship between two quantities related by one variable...
Perhaps by following the link above, and reading from there, you'll be able to get a better grasp on the subject.
But if you are then Fourier transform means something other than what I thought and so we're back at the beginning.
