SimBiology - Hill Kinetics
I am using SimBiology 3.1 for pharmacokinetic-pharmacodynamic modeling. I generate the models either within the SimBiology environment or programatically within a MATLAB script. My current model works well when the drug concentration vs. response relationship uses a standard Henri-Michaelis-Menten KineticLaw (for a sim... 9 Apr 2010 17:51

easiest way to set path/defaults with windows7 permissions?
I recently upgraded to windows 7 and 2009b, and aside from the problems this bug is bringing me (http://www.mathworks.com/support/bugreports/582876), I'm having trouble keeping my path and default path when I open. I File>Set Path, save, and because of permissions I now have to save pathdef.m somewhere. I put it in D... 7 Apr 2010 15:45

overlaying images of different sizes
I have two images, one acquired at a resolution of 128*128 pixels, and another sampled at 8*8 with a much lower resolution technique. Both display just fine separately using imagesc, but when I try to plot one, then use "hold on" the 8*8 image just plots in the corner of the 128*128 image. How can I get them to display... 30 Apr 2010 10:35

Scaling of the spatial variable in function radon
Greetings, I am trying to figure out the scaling of the vector r (or rho, xp, affine parameter or spatial variable in the Radon domain) in the function *radon* that would be consistent with the analytical Radon transform of a function we already know, e.g. the Radon transform of the unit circle. What would this sca... 7 Apr 2010 15:45
