Hi,
I am having a 3 2d matrices
1st matrix is of size NxM corresponds to the X-cordinates
2nd matrix is of size NxM corresponds to the Y-cordinates
3rd matrix is of size NxM corresponds to the Power at the above designated cordinates
How to find the Total power and total power above half maximum?

Isn't the total power simply the sum of the powers? The half maximum of what?

Hi,
Integration is equivalent to summation in the discrete domain. So, if P is your NxM power matrix, you can compute the total power and total power above half maximum as follows, assuming the power is in watts.
totalPower = sum(P,'all');
maxPower = max(P(:));
totalPowerHalfMaximum = sum(P(P>0.5*maxPower));
