This and MATLAB.

I haven't used a calculator since my second year of undergrad. They are slow to use, purposefully stunted in features, and generally pointless.

Only thing they're good for is for exams, because modern-day students can't be trusted not to cheat. And, there are many situations in which a graphing calculator could allow you to cheat, anyway, so it's often banned then.

about Matlab I need to bullshit, sorry for leaving that out

Does anyone know how I can animate a motional process (in this case gondola lift, modelled as double pendulum) with Matlab using the solution matrix of the ode solver and overlaying image files.

So far I have an animation using two line segments. This was relatively easy to do but now I'd like to replace those line segments with graphics of the system.
I made a vector graphic image of the system with inkscape but I think it should be easiest to convert the two bodies involved in the movement (mounting bar and cabin) into separate pngs and using my solution vector to position those images. The thing is, I have no idea how to do that.

Any ideas? (further pictures incoming)

Is there a STEM major out there who doesn't know MATLAB?

Can anyone recommend me a resource for Matlab exercises? I have googled, but not really found anything that I think will be particularly helpful. I'm specifically looking for some sort or scenario from which I have to work out what sort of script to write, I think this will give me practice best. I'm basically a beginner, the most complicated thing I've done is compute erf(x) using Simpson's rule, so nothing too hard pls.

Hey /sci/

Basic MATLAB question.

Is there a way to find out the index of a matrix element by inputing its value?

e.g.

mat = [12, 87, 34; 39, 25, 98]

findindex mat(87)


ans = (1 , 2)
