Any ideas why it isn't showing the top two? for t = 1:39 scrsz = get(0,'ScreenSize'); fh = figure('Position',[4 scrsz(4)/1.5 scrsz(3)/1.5 scrsz(4)/1.5]); ... 8 Jun 2010 18:20

Have fminunc show the gradient?
Hi! Thanks for the help, it was very useful! I have a related question: Is it possible to save the gradient so that I can see it in the workspace, rather than just display it for each iteration? I defined it as an output of outfun by: function [stop,Y] = outfun(x, optimValues, state) stop=false; switch sta... 8 Jun 2010 18:20

Setting ROIPosition in command window
I am using 2009a. Since the Image Acquisition tool will only display one camera at a time I need to write a script and run it from the command window.

symbolic toolbox and differentiate
Hi everybody, can you help me to write MATLAB symbolic commands to calculate this differentiate problem? AA[i,j] is my favorite answer: (this is a pseudo code) ******************************************** q[i, j] := exp((a[i]-a[j])^2)/(symsum ( symsum((a[i]-a[j])^2, j ,k,n), i ,k,n)) k[i , j] := symsum( sym... 8 Jun 2010 16:01
