Area under the curve using ginput

Hello Everyone,

I am trying to calculate the area under the curve specifically between the two points which I assigned during the calculation of higest value.The code is as follow for better understanding :

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

% Area

x = y;

y3 = 30 - 60 * cos(2 * pi / 100 * y);

A = trapz(x, y3)

So, I need help with calculation of area under the curve between the same points which I described earlier during the calualtion of highest value coordinates using the ginput.Any help would be appreciated.

%% In this code area under the two peak use

Area=trapz(Peak)
