    C/C++ How can I perform symbolic computation in a C++ program?

    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...

    Simple cantilever beam question

    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...

    Simple cantilever beam question

    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.

    Simple cantilever beam question

    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?

    Simple cantilever beam question

    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...

    Uniqueness and existence of simplified equivalent circuits

    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...

    Uniqueness and existence of simplified equivalent circuits

    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...

    MATLAB Why does this Matlab snippet create biased Fourier waveforms?

    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!

    MATLAB Why does this Matlab snippet create biased Fourier waveforms?

    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...
