MATLAB: How to get an X value between a specific set of Y values

biggest value between x and ydata setmax valuerange

Hello. Lets say I have X and Y values as showed below.

How can I tell matlab to give me the biggest Y value between X values of 6 and 16? Answer: 100

Thanks!

Assuming that X and Y are variables in their own right:

max(Y(X>=6 & X<=16))

 [~,idx] = max(X);

Note that this returns 1 for columns that are all zero.

Just get the min and max value of your new array J

minJValue = min(J(:));
maxJValue = max(J(:));
imshow(yourOtherImage, [minJValue maxJValue]);
