read vrm in malab
Hi there, I am not sure what you mean by reading in a VRML file. The VRML file is a text-based file with a very well defined format making it amenable to parsing. 1. If you want to view the VRML file from a MATLAB file and animate it, then see the example here: http://www.mathworks.com/matlabcentral/fileexchan... 30 Jun 2010 04:20

Hi Edric, Sorry for the lengthy delay in my reply--I had originally forgotten about this thread, but then found it again when I was searching my inbox for another thread. I think the biggest problem the documentation didn't explain (or at least, I couldn't understand from the documentation) is the codistributor o... 29 Jun 2010 19:36

how to control coefficient of transfer function in Simulink?
Hello in my model, I need to use a simple transfer function block : 1/(s+1). I am trying to control the coefficient of " s" only, to control the slope of the output curve. since I am running my model in real time windows target, that coefficient needs to be a variable that changes during the simulation based on th... 29 Jun 2010 19:36

Passing integer arrays through mex to ifort
Hi, I am trying to pass integer arrays through a mex wrapper to ifort. The arrays hold indices for a real array I will access. Can someone post a sample of how to do this? I did not find example in the sample files. Another alternative would be to convert the real arrays to integers. I have yet to figure ... 29 Jun 2010 19:36

Simple matricies
I am trying to create a matrix which is 10x10. The first row should go 1:10, the first column should go from 1:10 (downward), and a diagonal 1:10. I have it seperated as A = 1:10 A' B = diag(A) how would i combine these matricies so i wouldnt still get a 10x10 matrix? ... 29 Jun 2010 18:30

Simscape Simhydraulics - Hydraulic Fluid
I'm trying to vary the temperature of my hydraulic model with time. The only way I can think of is to vary the temperature of the hydrailic fluid block, however it only seems to accept a singular value for temperature. Any help on this subject would be appreciated. Other suggestions are perfectly acceptable (... 13 Jul 2010 11:59

find / ismember / index within structure array
Hey! I'm a frustrated MATLAB beginner and need some help. I have a structure array containing two double arrays and one cell array: S = [127x1 double] [127x1 double] {127x1 cell} The cell array contains the information (strings) that I'd like to classify/find. The two double arrays contain the r... 29 Jun 2010 19:36
