pixel list from bounding box?
Can anyone suggest a better way to do the following? I want a pixel list (x,y), not linear indices, of a region in an image specified by a bounding box ... Below is a for- loop sort of brute force approach, but I get the impression this isn't a good way to do this in MatLab. Any advice? function [xlist yl... 24 Jul 2008 12:54

Hi, I have just a small problem. What is the matlab-command to "expand axes to fill figure". This is a check- box in the Export-Setup of figures. Even after searching very long, I didn't find a solution how to write it in a Matlab-Code. Thank you very much!! ... 18 Jul 2008 13:24

xcorr (cross-correlation)
Hi, I am using the function xcorr (cross-correlation)as follows: c = xcorr(x,y,'coeff') by using 'coeff' it normalizes the sequence so the autocorrelations at zero lag are identically 1.0. I would like to calculate the cross-correlation coefficient between vectors x and y at different lags but without n... 21 Jul 2008 13:04

Can pdepe handle coupled eqns?
Hi, I have the 2 eqns ( D denotes partial derivative): DpDr=v^2/r with p(1)=1; DvDt=(1/r)DDr[r(p+1)DvDr] + some fn of p,v. bc: v(1,t)=1, v(2,t)=0 v(r,0)=0. So m=1,c=1,f=(p+1)DvDr s=...etc. But how do I handle the first eqn?I only have one boundary condition for it.Can i solve these 2 together with pdepe?please s... 10 Jul 2008 01:01
