quad2d and singularities
Hi guys, I'm trying to compute the below double integral with variable limits using quad2d; quad2d(@(u,v) (1./u).*lognpdf(1./u,mu_a,sigma_a).*(1./(1-logncdf(((1/mc).*(delta.*(1./v)+c*(eta/(1-eta))*chi*theta-(c/((1-eta)*q)))),mu_a,sigma_a))).*lognpdf(1./v,mu_h,sigma_h).*(-(1./u).^2).*(-(1./v).^2).*(1/(1-logncdf(... 25 May 2010 23:26

clustering 'locally' for large data set?
Hi Folks, I have a list of 10^3 to 10^6 positions that I would like to use for cluster analysis. I have been using the function clusterdata... T = clusterdata(X,'distance','euclid','linkage','single','cutoff',... distance_threshold,'criterion','distance'); Not surprisingly, the analysis doesn't work beyond... 28 May 2010 14:51

tick label in a polar plot
This does not seem to solve the problem. It replaces the labels with new labels, however the default is 30deg increments. Therefore the 45deg increment is not set. Is there a way to do 0.45.90.....? The only way I can think of is manual text placement "us " <us(a)neurol.unizh.ch> wrote in message <hi8cl7$mta$1... 26 May 2010 16:55

LSQLIN: issue with residual norm
lsqnonneg works fine and returns resnorm of 9 10^-8 while lsqlin returns peaky solution and the resnorm of 1.12 10^-5. The returned solution in this case is ok, not as good as in the case of lsqnonneg. Since the problem is large scale, I am under impression that I can not use lsqnonneg. I would like to use lsqlin... 26 May 2010 12:27

LaTeX usepackage
I'd like to use some LaTeX math symbols from here: http://www.ams.org/publications/authors/tex/amsfonts such as "\blacksquare" and "\lessdot". I'm able to use function TEXT to get the usual LaTeX and math functions to display properly, but I don't know how to be able to specify tags in a package that isn't a... 27 May 2010 08:09

transparency interactions
Hi everyone, When I use the patch command to create a transparent patch, the transparency of the patch interacts with subsequent plot commands in a way that is (to me at least), unexpected. My expectation is that subsequent objects will simply be drawn "on top" of the patch. However, subsequent plot objects seem... 25 May 2010 16:51
