optimization of fiber bragg grating using nelder-mead simplex algoritm
can someone help me to optimize the fiber bragg grating(fbg) using nelder mead simplex algoritm. i have both codes (both codes working well) the fbg n nelder mead but i fail to integrate them. the parameter that i want to optimize are the length (L), period (A) and the induced index change (dn). so here are the codes ... 4 Apr 2010 11:30

imagesc
Hi all, I read in a matrix from xls file. The matrix is as follows pvalue = [ NaN NaN NaN NaN; NaN NaN 1.00000000000000e-05 NaN; NaN 4.00000000000000e-05 0 NaN; NaN 0 0 NaN; NaN NaN NaN NaN]; Those NaN elements are empty in the excel file. As all the pvalues are >=0, I set NaN elements to -2, and set caxis... 4 Apr 2010 13:42

Fitting for multiple distributions
Hi, I was wondering if Matlab has a way to fit data for several distributions. I have yeast cells, some of them displaying basal gene activation which results in a very tight Gaussian distribution around zero. Other cells have genes activated in bursts and have a Gamma or exponential distribution activation. I woul... 7 Apr 2010 10:04

Matlab pdist function and c++ implementation
I am trying to write a function in c++ that does what pdist function of matlab would do. I have used the exact same code as is used by matlab in the c file. However, after compilation in release mode with all optimizations enabled, I don't get the same speed as in matlab, at least three times slower. Has anybody ... 4 Apr 2010 06:06
