At what point does matlab becomes a restriction in terms of size or speed
Let me clarify ... we (some coleagues, not important here) were discussing how matlab is nice and everything (it is really), but at one point in terms of size of data it needs to process, or speed of doing it, it becomes a restriction as compared to let's say fortran. Then another fellow asked, at what point does... 28 Apr 2010 17:26

shade some zones for emphasis
Hi all, I have a plot need some shade zones for emphasis. I can find some useful code to emphasize the time series, however I can't find one for emphasis the Y axis. For example, I like to emphasis [Y1 Y2], [Y5 Y6] and so on. Here, Y1 = 5, Y2 = 10, Y5 = 30 and Y6 = 40. Thank you. ... 27 Apr 2010 09:52

Binning/averaging/condensing environmental data
A very straightforward question I think, I've just not been able to find a solution I fairly high frequency (~10 measurements/minute) multiparameter environmental (temperature etc) data that I need to condense. At the moment I think I would like a mean value for each parameter every minute. How should I go about do... 18 May 2010 13:39

Filter command for MIMO
I have a Multi-input output system. After creating the ARX model, I want to validate the model prediction using the filter commands. However it gives me this error. m is the model. U is the data set. M looks like : Multivariable ARX model A0*y(t)+A1*y(t-T)+ ... + An*y(t-nT) = B0*u(t)+B1*u(t-T... 27 Apr 2010 11:01
