Don't know where else in Phyiscs Forums or on the internet in general to ask this, and if it's inappropriate here, I apologize. My question is: is there an open source library or resource that I can access from a C++ program to perform symbolic computation on the level of something like Maple...
I'm confused too, and I do appreciate the time that you're spending on this.
I've taken basic diff eqs, but this seems to be much harder than I would have expected, very different from forced springs and similar things. Now I'm starting to see why it's not just right there in any textbooks...
Thanks for the replies~
So at any rate this does seem to be somewhat beyond "Cantilever Beams 101" and the type of thing that would be listed in any textbook. OK, well let me take a look at what's been posted here and see if it makes sense.
OK, I appreciate the encouragement but this is not a homework question and physics/engineering is not my field. Surely this is in a textbook somewhere? I'm not sure why I can't find it. Any ideas?
I've been looking at the equations describing different aspects of cantilever beam dynamics, but I can't seem to find what I'm looking for. (And I'm not smart enough to derive it.) If I pluck the tip of the beam and measure the location (x) of the tip over time (t), it should look something...
Thanks very much for your reply. I actually am only thinking about 1 input, 1 output circuits. You're absolutely right, this is part of a black box modeling project. Based on your advice, I probably will rethink my entire random circuit idea in terms of random transfer functions instead...
I know this probably sounds weird, but I have a research problem that requires "random" analog circuits. Basically what this means is that I create Spice netlists by randomly adding linear and/or nonlinear components of random types with random node and parameter values. This works fine and I...
Actually, phrasing the question forced me to take another look at my code and I discovered that I was multiplying everything by another factor, unlike in the code I actually posted, so there's no bias anymore. Thanks anyways!
Why does this Matlab snippet create "biased" Fourier waveforms?
I'm trying to search through the space of all possible waveforms (or a reasonable approximation of that space), where waveforms are described by 20 parameters: the first 9 Fourier coefficients for sine terms a(1:9), the first 9...
