Hi, I am new to matlab and want to run some correlations of data over time and see how they change. I want to run the correlation between 2 time series over a 200 period window and save each correlation value to a new matrix so I can then graph the resulting correlations. I know this should be easy but I am stuck,... 17 Jul 2010 01:16

image rotation puzzle
I have a 2D circular figure that is essentially a spline. I have a set of points (x, y) that lie along this circular spline. Now I take this figure and put it into 3D space with its center at a known point in 3D space. I also have a vector normal to the circular figure that defines the orientation of the circular fi... 16 Jul 2010 17:40

LSODA solver implementation in Matlab?
Howdy Folks, I'm trying to help someone convert a ODE based model from one software package to another. The other software package uses the LSODA solver [1]. Her system is pretty stiff, and I could get it to solve for one set of parameters using ode15s, but I had to switch to ode23s to get it to solve with a dif... 16 Jul 2010 16:34

simulink model and processor model integration
hi, i am trying to work on a combined model of different automotive components whose models are freely available in matlab simulink. with this system, i would like to add a processor model, where i would like to write a code (i assume it typically to be a simulator of that processor). is this interfacing of simulink m... 18 Jul 2010 11:36

Import multiple figures to Excel using VBA
I would like import the MULTIPLE figures (around 100) I generate in matlab to excel. Using MLGetFigure in VBA only imports the current figure and does import all figures. Is there a way to grab all figures? If MLGetFigure took a figure number as a parameter, it would be easy to loop though them in VBA. Any ideas?... 16 Jul 2010 15:27
