Urgent....D operator in matlab
Does anyone know about differential operator in MATLAB corresponding to "D" operator in Mathematica. I am not looking for diff() function. I just want to use d/dt corresponding to "d/dx" used in mathematica. I want to use this "d/dt" operator in Bessel function: 1+sigma*D/a... 7 Apr 2010 13:29

HDMI Image Acquisition
I was wondering if anyone has used the Matlab Image Acquisition toolbox to capture HDMI video sources. If so, can you post what hardware you used? I have not been able to successfully communicate with any HDMI acquisition hardware that is capable of 1920x1080 60fps. I have tried AJA Xena LSi card mostly. ... 6 Apr 2010 20:58

Nonlinear optimization, confidence interval, observability
I'm trying to optimize the parameters of a model so as to minimize the difference between measured and predicted values. I'm able to compute the confidence interval for each parameter. 1) Some parameters have large confidence intervals (basically related to the upper and lower bounds provided as constraints) ... 6 Apr 2010 18:42

How to control Matlab's printed number field width?
Is there any way to force output of g and f format to stay within the specified field with. This is giving me trouble all the time and at ever unexpected locations when preparing input for fortran programs that require 10 width numbers Matlab is completely uncontrollable in this respect. Writing my own formatting fu... 6 Apr 2010 18:42

How to find (and plot) surface normal
Hey, I have a 3D point cloud. I need to create a surface mesh and find the normal vector to each vertex. I wrote a very naive method that: -- finds the normal vector of each triangle in the mesh -- finds the neighboring trinagles of each vertex -- returns the sum of all the neighbors' noramls as the vertex n... 20 Apr 2010 15:53
