Accessing Dialog Parameters for a Level 2 M-File S-Function
Hi All, I'm trying to generate code for a simple model which has a Level-2 M-File S-Function in it. My S-Function takes in one parameter from the dialog box which is used for some computation. I understand that I have to write a corresponding .tlc file to tell RTW how to generate code for this S-Function. My questio... 8 Jul 2010 01:33

Opinions on 'resample' function?
Hey everyone, Does anybody have any opinions on the usefulness of Matlab's 'resample' function? I've noticed that it tends to do a decent job of resampling in the initial portion of my signal (I'm referring to the time domain), but towards the end my resampled signal ends up leading in front of my original signa... 7 Jul 2010 12:21

Vector Field
I am really new to programming and need to create a vector field. It seemed simple enough however I am running into problems. I have three 224x224 arrays, one in the x, y, and z direction. When I try to use quiver to either do the vector field of 'xy, I only get a straight line and also when I do quiver3 I get a str... 7 Jul 2010 12:21
