Hello All, Can anyone please advise what is the best way of creating a 3d multilayered structure in Matlab? I need a 3d model of skin for Monte Carlo simulations. So, I am thinking is it easy enough to create the model directly in Matlab or to draw it in CAD (or find an image), and then convert the image to the Matlab file? Thanks a lot Irina ...

Hello, I have a 3d model of a human face, loaded on MATLAB. The object is on a Nx3 matrix, like x1 y1 z1 x2 y2 z2 x3 y3 z3 (...) each row is a point of the structure. How can I put this to a surf object, so I can apply a texture afterwards ? ... I can see the model by patch command (e.g patch(points(:,1), points(:,2), points(:,3),1)) Please help! Thanks in advance! Nunes ...

I am trying to run a simulink model simulation in definite time steps from MATLAB so that I can extract data from simulink, do some caluclations and send these new data back to Simulink for further simulation from the point I left off. The process can be descirbed below: Note that total simulation time is 600 seconds. 1. Start simulation from MATLAB for 100 seconds and then pause the simulation 2. Extract all the data I need from simulink and bring into MATLAB, do some calculations to changes simulink model parameters and then pass this new calculated data back to simulink. 3. Continue the simulation where I left off (i.e. from 100 seconds) but this time in 15 second intervals, up to total simulation time end (repeating step 2 and 3 after every 15 seconds). Can someone please advise if they have done this before and what command structures they used. Thank you. True. You can "sim" to achieve this. Try "help sim" to learn details.

I am currently programming a model of a finite quantum well and have run into a couple of problems. After applying boundary conditions, I get two equations: tan(theta) = sqrt(theta_knot^2/theta^2 - 1) cot(theta) = -sqrt(theta_knot^2/theta^2 -1) The parameters theta and theta_knot have the width of well, barrier potential, and mass of the electron embedded in them. I tried solving this in two ways: 1) I arranged loops to solve using the "solve" command for transcendental equation but the cotangent argument was causing a problem. 2) My other attempt consisted of incrementing ...

How does MATLAB's C code store information in memory, cache'ing etc? How is one to get at those? Do you know of any suitable reference(s)/resource(s)? Thank you very much, Aravind ...

Hello I need to build a model of half sphere. In the model I want to put a "hot point" and to give to each point on the surface it value according to his distance from the hot point. I assume that the value on surface is proportionate to 1/(D^2), where D is the distance from the hot source. Afterward I want to look at the model from different direction and to get the picture of the object I get from this point (2D image). My questions are: 1. Is Matlab Is the right tool to do this? 2. If it is, how do I do it? Thanks a lot Ditza ...

I'm making an end-user application where I would like to use Matlab functionality both for calculation and plotting. Matlabs GUI builder guide does not satisfy my needs (no support for f.ex. internal frames and other nescessities), so I'm planning to compile my Matlab code and use other API (Java, QT or something) for GUI. My problem is then, that I loose access to the neat plotting commands availible under matlab GUI... Is there a way of integrating Matlabs plot functionality into another GUI system? - has it been done? - I appreciate any response! - P�l Berge ...

Hello everyone, How do I compile MATLAB M files into a form that can then be called from within the MATLAB interpreter? A roundabout way would seem to be to (somehow) Turn the matlab code into C (I think mcc does this), then compile this C code into MEX format and call that. Is there an easier way? I have the MATLAB compiler, so I just need to know what to do with it to get this to work.

Hi All, I am trying to plot a 3D grid onto a 3D image in Matlab. May I ask how to do it please? For example, I have got a 3D image with 201x201x201 voxels. I want to plot a 3D grid with 10 voxels spacing on to the image (there will be 21x21x21 cubes to form this 3D grid). I have got the coordinates of the grid in three matrix X, Y, and Z all sized 21x21x21. Then I want to plot both the image and the 3D grid using a Matlab function slidingviewer(...); at FEX. Here is an illustration of the image I want to get. NB: the grid has no need to be regular. http://i54.tinypic...

If I type the above load command in MATLAB 6 I get and error. Is there anything that provides the technical information for this? Thanks Dave Dave wrote: > I am looking for information here on t...
