Hope this gets buried shortly.

But anybody here good with MATLAB or know of a good resource (on campus or off) to work with?

Watching lots of Youtube videos and everyone does the same kind of problems differently. :(

I used to go to the labs in kaufman. All their computers have it and usually the person in charge of the place is a TA who knows how to use it. I used that and the textbook to get through it. However this was back in 06-07 so I'm not sure if has changed.

Also you could try reddit too. I haven't really looked but there really is a subreddit for everything.

Was the same when I went back in 2015.

Ghentfan, wish I could help more, but I took one class on it and that only really scratched the surface. What exactly is the issue you're encountering?

I'll try the lab in Kaufman.
Last time I went there though the person there said he was only a babysitter for the computers and had no idea how to use any of the programs.

It's simple things that I'm trying to understand more.
Differentiation for example.
I fully understand having to do the syms x command.
In the book I'm using the command is just to do yprime = diff(y)

No big deal right?
But this video does it different. Again, no big deal. I'm sure there are many ways to do simple operations like this.



The problem is having to answer problems like this.

8-23. Consider the running integral. z = ∫cos(x) dx (from 0 to x)
a) Determine the exact value
b) First-order approximation over one cycle based on a step size of 0.01π (pi).
c) Plot the approximation as a continuous curve and the exact value as a sequence of o’s.

a) >> syms x
>> z = int(cos(x))

z =

sin(x)

>> z1=(sin(x)-sin(0))

z1 =

sin(x)


b)
>> delx=0.01*pi; %0.01 = the number of steps
>> x=0:delx: pi/2;
>> y=cos(x);
>> z=delx*cumtrapz(y);
>> plot(x,z,x,sin(x),'o')
>> xlabel('x')
>> ylabel('First Order approximation')
>> title('Problem 8-23 plot approximation (line) and exact values (o)')

I don't fully understand the delx command, or why the domain is pi/2 vice simply pi.
Why don't I just use the linespace command?

Also, M files. But I guess that's just practice.

Were the mid-terms and finals done on Matlab? Paper and Pen?
I can do the math on paper with out issue. 3x3 Matrix sucks though.

Haha I remember taking the course but haven't touched it since 2009.

Yes it's for EET 305.
It's cool. Thanks anyway guys!

Is this for EET 305 (I think that's what it was)? If so, I think part of the mid-term and finals were done in Matlab, but not the whole thing. Devyanks was in the classes with me...maybe he remembers better?

Otherwise, sorry for not being much help. Good luck!

There are a few commands like "special"

Pretty
Cumsum
trapz
cumtrapz

Are you studying MET and taking EET as a side course ? Or studying EET only? Also if you bought the book as new, usually it comes with a MATLAB CD and 1 year free registration(I think so) . Back in those days I used to help my EE friends with matlab, damn Its been nearly 7 years since I touched on this, wish I could help you but I'm out of touch.

For us mathlab was given as takeaway exam for finals and midterm. The rest was on paper in class.

I'm taking MET courses right now to get into the Robotics/Automation classes. EET305 is a pre-req for a bunch of the classes as I need to know MATLAB for those and other master level classes that touch on the subject.
EET305 I is required for CET,EET, and MET.

Any of you guys know what courses teach PLC's? I'm trying to get better with those next.

Yup I knew it. Who is the head of the department right now, is it the Taiwanese American prof? Mr Lin or something ? If you have classes with him, try making friends lol and he is a great guy. I had some hard time getting into pre-req classes and took me extra semesters to complete. Would have taken me more but other profs and Mr Lin helped me out registering for classes. Met is fun, expect for mutaffa's class. He is a bad advisor as well. That guy is boring and favours only his likeable students. I don't know if he still teaches there but try to avoid his classes.

I appreciate the info! :)

Yes, Dr. Lin is in charge of the MET program. I've already been working with him in the past. He waved a few of my classes after sitting and talking with him regarding my past experiences, what I do currently and my goals. He made me prove my knowledge though :)

I'm also working with Dr. Hou in the ME program.

It might seem like I'm all over the place, but long story short. I'm an Electronics Tech pursuing the Mechanical side of things and I plan to take both halves to better understand the automation mechatronics world. After the Masters in ME I might stick around and do a doctorate in Systems Engineering. I haven't quite made up my mind yet.

Since it seems that a few of you guys did Engineering Technology I figure I'd share a list of Masters Degree programs that I had made.

I had been considering University of Houston's MET program as it touches on the oil field (My industry), but opted to stay local and take what ever automation / Engineering programming classes I could here at ODU. Purdue and Drexe were also on my short list but I wasn't quite won over with what they had to offer.

I've passed this list to the Engineering Technology Department (Not sure if they kept it) and it's not complete, but it's what I managed to find in about 2 hours or so.

Sorry missed this post.
I bought the book new. There are 3 ISBN's of the book now. Newest edition no longer has the CD.
Also jealous of the take home test. We have 2 hours for 66 questions. Problem is part of the test is writing out the MATLAB portion. Not being able to look up the help function or get the feedback of a mess up is going to be a problem.
