CONLS (Constrained linear least-squares): What has this function been replaced with?
I would like to run some old MATLAB code found at http://web.archive.org/web/20011206005452/tigger.uic.edu/~olegb/research/PCA.txt which uses the CONLS function. I assume this function is part of some older version of MATLAB. What has this function been replaced with in R2006a? Could you please let me know the new f... 18 May 2010 15:53

Use save append option in a for loop
Hi MatlabCentral Members! For one of my research projects I have to deal with big matrices which are generated in a for loop. Since my memory is limited I have to clear my workspace before the next cycle of the loop can start. I asked myself if it is possible to save and append files with the same file name created ... 18 May 2010 17:00

Time interpolation
Hi all Another question: I have a list of sampling sites 's', (1992x1), the time each site was visited 't', (1992x1) and, for each site 12 measurements, taken at different times and from another dataset (each sample time is another list 'm1, m2, m3 ....' (1992x1) and the times of those measurements is given in 'Mt'... 20 May 2010 02:59

Generating parameter vectors for Rapid Accelerator mode
Here's where I'm up to with the PARFOR and the CAMM Seeker model: I'm working on configuring our model to run in Rapid Accelerator mode with the "RapidAcceleratorUpToDateCheck" set to "off", following the demo in the MATLAB help, but I'm having trouble. The main issue is that each simulation runs with the param... 18 May 2010 13:39

Copula pdf and copula cdf
Dear all, I would like to make surf and contour plots of bivariate copulas and have some problems with it since I do not know what the correct input data for these functions is. I have financial returns data of different assets, each with more than 1000 data points and have already estimated the copula parameters that... 6 Jun 2010 04:00

Interesting problem with image alpha data
"Michael " <michael.bennett(a)lineone.net> wrote in message <h1fj4i$7ln$1(a)fred.mathworks.com>... I have come across an interesting problem with setting the alpha data for an image, which I can't quite get my head around. To explain, consider the following example: h1 = figure(1); h1a = axes('DataA... 2 Jun 2010 10:54

fmincon
Dear Sir, i have to find the parameters for a real world plant. I have the real world data and i want to use fmincon to minimize the error between ymeasured-ysimulation. my function is f(1) = real world data f(2) = p1(x^2)+p2(x)-m*g e = f(1)-f(2) i want to minimise e and find the parameters p1 and p2.

OLS regression
Hi, I try to estimate the OLS by results=ols(y,[ones(T,1) x]); It wont work n i dont know why, I defined T, y, x and the equation. Matlab tells me ??? Undefined function or method 'ols' for input arguments of type 'double'. Error in ==> Monte_Carlo at 16 results=ols(y,[ones(T,1) x]); And i dont... 21 May 2010 10:35

Difference between image, patch and surface
Can anyone explain what the difference is between an image, patch and surface object? How do they compare for 2D or 3D plotting? (I want to display some images, with linear interpolation between pixels when they are zoomed in (so they always look smooth). I then plan to draw various other lines on top of th... 18 May 2010 13:39
