Constrained least squares with linear inequalities Hi guys, I have a simple example of constrained least squares that I am solving. The problem is min x'*x s.t. Ax<=b where A is a square matrix with tridiagonal structure. I have formulated the problem for use with quadprog but this feels to me like swatting a fly with a sledgehammer. I would appreciate any... 6 Aug 2010 09:21

why is for loop iterating by 2's ? Hello all, I have a for loop that seems to be counting by 2’s, I can not figure out why. I have some of the code below, I don’t think the while loop has anything to do with the problem I am having, but I will leave the beginning of it in the code I show you, just in case it is. As I said, the problem i... 6 Aug 2010 22:34
Thz signal generation using Cmos and linear superimposition Hi i am in a bit of a bother.I just found out about simulink last month.While trying to simulate Thz cmos circuit I encountered several problems. Problem 1:why does red dots appear instead of black wires while connecting two devices. Problem 2:how do I simulate a rectifier.At first they want me to use powergui block ... 6 Aug 2010 03:54
splitting for self avoiding walks Hi. I need some help to simulate some special self avoiding walks. Let's start with say 100 simultaneous runs. After 2 steps, say 75 of them were still alive and 25 went backwards and were "killed". Since 75<100, duplicate each one not killed twice (to get 150 runs). Continue and each time the number not killed get... 10 Aug 2010 00:28
find statistics of a matrices i have a matrix of doubles, and would like to find the statistics of each number or in other words, to find how many times each element has been repeated across the matrix and plot it. i have a solution with for loops but it's too slow. i am looking for a matlab solution that is not based on nested for loops. ... 9 Aug 2010 05:45

Need help: ROC curve Is anyone have matlab code to generate ROC curve from a similarity matrix calulated from all pairs of target and query images using specific distance measure in terms of face verification task (like wt BEE do in FRGC). I have been searching the internet for code or algorithm but have no luck. It will be ver... 6 Aug 2010 02:49
Not displaying graphs Hi, I am running a large amount of simulations that involve plotting graphs and saving them to disk. Using figure() and plot() followed by saveas() My question is, is that it seems a lot of time is being spent in drawing the graph on screen, I only need it to be saved to disk. Is there anyway to save the graph... 6 Aug 2010 06:04 |
