Matlab Project for Linear Algebra Course

I need some Matlab help for a Project I'm doing in a Linear Algebra class I'm taking. Could someone help out?

[Matt Kindig]

What have you done so far with your assignment? Where are you specifically stuck in Matlab? Can you show us your code so far?

[Hosnel]

Luffy Answered the portion of the question I had already figured out. It's part (B) is where I get stuck at. I'm unsure what the professor is asking for. Has anyone encountered such a problem before? If so HELP!

surface is a type of 3D plot you have to do for the mentioned question for the 3 parameterts mentioned you have to plot the surface plot, its a type of 3D plot like like plot where u plot plot(x,y) it has three parameters (x,y,z)and you can animate by holding

I just asked the professor, he did some more clarification on it. Apparently, my partner had missed some more information... Here it is:

Answer 1

[Sean de Wolski]

Since you seem to be looking for the ez way out:

syms x y
ezsurf(2*sin(x*y),[-2.5 2.5])

Answer 2

[Luffy]

 What is M(Y),M(R),M(P) in part B??
 For A) part,
  x = -2.5:0.001:2.5;
  y = -2.5:0.001:2.5;
  z = 2*sin(x.*y);
  plot3(x,y,z);
  grid on;

[Hosnel]

Thank you Luffy, you definitely clarified that I was in fact in the right directions as for the (B) part, I am unsure as to what he actually expects. That whole equation looks new to me.

The best way to find out what the professor wants for (B) is to ask the professor.

The images are no longer available from photobucket.

[Hosnel]

Reloaded the image...

[Walter Roberson]

Okay, so what are the M matrices ?

[Hosnel]

I'm really trying to get this, I don't know why someone has flagged this for deletion. I thought this was a site to help with Matlab work.

Anyway...

I'm guessing its a multiplication of three different Matrices. | M( Y )*M( R )*M( P )*S|

Where Y is Yaw, R is Roll & P is Pitch. I would definitely be able to do this on paper, but when it comes to Matlab, this is a foreign language.

@Hosnel: there is a huge difference between helping and solving from scratch an entire homework YOU are supposed to hand in.

[Hosnel]

Are you serious? I'm sure this site was created so that people with nohow can help those without. As I posted, the professor gave us a project to work on, but didn't give us the adequate foundation to solve it. That's why it's a class project, that I am working on with my two other partners (sitting right next to me). This is a linear algebra course, but we are doing different problems using Matlab, which is not the brunt of the work. I didn't know that knowledgable people like to withhold information. Each one teach one! Thanks those that were helpful.

[Walter Roberson]

You still have not indicated what M is.

[Sean de Wolski]

We're more than willing to help but not more than willing to doit4u.

What have you done so far? What effort have you expended on your project?

[Walter Roberson]

We can invent any number of meanings for what M subscript gamma means, but the probability that our inventions will happen to match what your professor wants is somewhat low. If you have not found out yet what the M refer to, it would probably be more effective to ask your professor than for us to give you a meaning that later turns out to be something rather different than what was desired. If you have found out what the M refer to, it would definitely be more effective for you to tell us than for us to continue to guess.

Note: This site is for questions about MATLAB, not for questions about linear algebra. When you have the meaning of your assignment sorted out, and have specific questions about how to translate that meaning into MATLAB notation, then we can help out with that.

One step: the MATLAB notation for the matrix multiplication of A with B, is A * B
