Any NSers know how to use MATLAB? I'm taking a course on it this quarter and have a few questions about it. I can't meet with the prof/TAs until later this week so that's why I'm asking here
I, personally, have not taken any classes yet that have included MATLAB. However, I have some friends in engineering that are a little ahead of me that have taken classes that utilized MATLAB. I can relay the questions you have to them if you'd like me to get some answers for you.
Basically I have to write a code for some matrix multiplication. The code is easy, but I have to make it save my answers and then upload the code to a website and the website grades it automatically. I'm having trouble getting the website to read my answers. I'll go into more detail when I'm not on mobile
on a general note, matlab is one badass program. idk what shit you cannot do with it.
used it for my master thesis, programmed a artifical neural network with it, with maybe 40 lines of code (most is generated by the ANN wizard). doing that from scratch with C++ or whatever is probably a bazillion lines of code.
legit program is legit.
@OP, isnt your problem more a problem with your schools webserver or what?
mechanical engineer, I know a bit of matlab. There is a ton that can be done with that program though, and it does become pretty intuitive once you get used to it. A while ago we did signal coding and matrix operations with it, like basic multiplication. Now we use it a bit to do regression lines, and we had a few projects on modeling the motion of a piston and resultant forces/motions. My teacher showed us some of the stuff people do with it though, and it is absurd. I can't seem to find it now, but there were animations of models of elastic materials, all color coded for a specific parameter. I would hate to create it, but it was really cool to see.
ive used it a bit, found it useful mostly for PID controller theory and frequency response /bode plots /root locus of higher order systems. i hate coding stuff with a passion, and although matlab code is super easy compared to most languages i still try to avoid it. that being said, i realize how valuable a resource it is and i should probably get better at using it. i torrented the full 2013 version last year so it should still be on the pirate bay.
B-WaldLooks like you don't have 4 arguments in the ode45 call. The left side of the equation has 4 variables, and you only have 3 on the right side.

You can have functions that output more variables than there are inputs, which I'm guessing is this case.
yep, i used it a lot at my old job. if you have a problem or question, what you wanna do is walk down the hall to kathy's office and say kathy im a retard and can't figure out this move in MATLAB can you come save my ass again? thanks
