I have two vectors, charge 'q' and corresponding phase angle 'Ph', each of size 899095x1. 'Ph'- min=0 degree, max=360 degree & 'q'- min=-4e-12, max=4.5e-12. I want to plot two distribution curves, in which the x-axis is my phase angle vectors which is divided into small phase windows of width,say 1.5 degree. One distribution curve should have X axis from 0-180 and another distribution curve having X axis varying from 180-360 and y axis(for both curve) : 1. number of charges present in that phase window. 2. sum of charge values observed in phase window. 3. average value of charge value observed in phase window. 4. maximum value of charge observed in phase window.

If I understand what you're asking I believe some combination of HISTOGRAM and/or ACCUMARRAY will do what you want.

Maybe this:
histogram(yourChargeArray); % Display histogram
countOfCharges = sum(yourChargeArray(:) ~= 0)
totalCharges = sum(yourChargeArray(:))
averageChargeValue = mean(yourChargeArray(:));
maxChargeValue = max(yourChargeArray(:));

By doing this, my x-axis won't be the phase angle. I want my x-axis to be phase angle vectors which is divided into small phase windows of width,say 1.5 degree and Y axis should be the count of charges or maximum charge magnitude or average of charge, within that phase window.
