help for the peak sidelobe ratio (PSLR) in the radar system
Hi there, The PSLR is defined as the ratio of the peak intensity of the most prominent sidelobe to the peak intensity of the main lobe. I try to implement the PSLR to compare a reconstruted image with the originl one in the radar system... Can anybody give me an hand to show the correct way to calculate the pea... 3 May 2010 09:49

Question on neural nets?
I am a new to neural nets. I have some data and targets with which I have learned some neural nets, like this: stage1Net = create_pr_net(s1,tar1); outputs1 = sim(stage1Net,s1); function create_pr_net(inputs,targets) numHiddenNeurons = 20; % Adjust as desired net = newpr(inputs,targets,numHiddenNeurons); net.di... 3 May 2010 09:49

Help needed here!! Using a camera to move the mouse cursor
I need advice on the suitable filtering techniques and also a good colour and shape detection algorithm. I'm trying to use colour detection together with shape detection to create a computer mouse. Basically the idea is: camera detects a particular shape and colour and acts as a right/left CLICK. camera detects ... 3 May 2010 12:02

Sorting Question
The last time I posted I was trying to take elements in a grid indexed in cartesian coordinates and express those elements in a grid indexed in spherical coordinates. I did this by creating a fine spherical grid and using the interp3 function filling in this grid. The interpolation created bias in the statistics of t... 3 May 2010 13:09

Fast Matrix Exponential
Hi All, I was wondering if anyone out there knows a fast alternative to the matrix exponential function expm. Perhaps there is a mex file out there somewhere? The matrix I am considering does not have any special form, except that all its entries are real numbers. I have considered the expokit package, but was wonde... 3 May 2010 09:49

Conversion from narxsp to parallel form
I have simplify the actual problem. I am using narxsp to train my problem. Whenever I use d1=[0 1] and d2=[0 1], there is an error occurred when executing the conversion from narxsp to the parallel form. It says, "network contains a zero-delay loop". If I want to change my d1 and d2 (delay) value. How should I repre... 3 May 2010 13:09

voronoi cells in bounded surface or volume
What if the bounding surface is not convex ? The MPT toolbox only deals with convex polytopes, I think. I have a point cloud in 3D representing spatial positions of cell nuclei of an embryo. The overall shape is not convex (it's actually a sort of thick spherical cap). I got a tight tessellation of it through a ball... 3 May 2010 07:39
