Hello,
I am trying to find the max peak between two points on a graph, using ginput. In other words, I want to be able to pick two points and the program will tell me the max peak between those two points. Any advice?
Thanks,
Nathan

Do you want the difference between the peaks or just which one is the highest?

I dont know if this is what you are looking for?
c=rand(1,10) % generate some random data
plot(c) % plot the data
hold on
y=[];
y=ginput(2); % take two mouse inputs on the graph
[r,c,v]=find(y==(max(y(:,2)))); % find which one is higher
Peak=y(r,:) % output the highest value coordinates..
hold off

If you have the Image Processing Toolbox, use improfile to get the intensity profile on a line between those two points. Then just pass that profile into the max() function to get the max value and location of the max between those two point.
