Thank you Matt and Greg. That clears everything a lot! Anja

I have used MATLAB for few hours.So I don't know the differences between version 6.5 and 7.0.I want to use some codes of MATLAB 7.0, but they doesn't work in MATLAB 6.5.How to change these codes so that they can work in matlab 6.5.Waiting for your help. Thank you . The codes are like this .I think changing the function findPI may work ,but I don'y know how % PIfun.m % Evaluate a function used to find the PI-line, using Kyle Champley's % method. % % Adam Wunderlich % last update: 5/18/06 function y = PIfun(r,R,h,gamma,x3,sb) temp = R - r*cos(gamma-sb); y = h*((pi - 2*atan(r*sin(gamma-sb)/temp))*(1 + (r^2 - R^2)/ (2*R*temp)) ... + sb) - x3; % find_PI_Line.m % % Find the the parametric interval corresponding to the unique PI-line % passing through the point x for a given helical pitch. % This code implements the method of Kyle Champley. % inputs: P = pitch (cm/turn), R = helix radius, delta_s = s stepsize, x % output: PI = [sb st] % % Adam Wunderlich % last update: 5/18/06 function [PI] = findPI(P,R,delta_s,x) h = P/(2*pi); r = sqrt(x(1)^2+x(2)^2); gamma = atan2(x(2),x(1)); options = optimset('TolX',h*delta_s/100,'FunValCheck','on'); [sb,fval,exitflag] = fzero(@(sb) PIfun(r,R,h,gamma,x(3),sb),...

I don't have the answer to your question, but I'm curious what sort of block codes you'd like to MAP-decode. It's practical for small Hamming codes. A few years back near-MAP decoding of Hamming constituent codes in a turbo code configuration was popular for awhile, so you could try searching for those implementations.

This concerned all other AES implementations also. If you search in the net, you can still find it, because all FEX submissions are copied soon. Another tool, which uses a Java call from Matlab has been copied to this newgroup also. I had extremly tedious discussions about the risk resulting from a published program for AES encryption. The US government decided that it is a real risk, if somebody downloads the code from one of the 5 states belonging to the axis of evil. Anyhow, you can still download the detailed specifications as PDF from official sites in the US, because a PDF is covered be the freedom of speech. Even when you download Java, you have to confirm by clicking a checkbox, that you do not live in one of the evil countries. Then the 256-bit encryption is available, otherwise the key length is limited to 128 bits. Kind regards, Jan ...

But I face a problem which is it cannot do detection for the new image that browse from other file. In my m-file, I already set 12 different images in command slider, so when run the program it can do detection for each image in slider. But how can I make it also can do detection for the new image that had browse from file? I think maybe I need to add in the new image path to the slider command there. But I not really know the new image path in my code.. Any help and advice would be greatly appreciated. Elise ...
