As per my understanding, you calculated the area under the curve using MATLAB's "trapz" function and would like to calculate the volume under the curve using other inbuilt functions. Refer to the following sample code below which is using "trapz" and "integral2" functions and modify it...
How can I calculate areas between these unknown curve and line, see image. The line is not zero. How can I use trapz in this case? it would calculate the area under the curve from zero line Areas under the line should be negative 테마복사 theta=0:10:710; T=[0 15 813...

and calculate the area under the curves as follows: A=∫(x2−x1)dy=(−2y(y2−3))3 The area under the curve′A′here is a function of′y′because we did not specify limits. If we define the limits as[−1,1], the integral returns a value of: ...

my prof gave us hint, to calculate the area enclosed, you need to take to forward area subtracted by the backward area. And it is under "trapz" can you write the code for that? J K on 10 Apr 2013 my problem is similar to this. http://www.mathworks.com/matlabcentral/newsreader/vi...

trapz(de)- Calculates the area under the curve of the trajectory. This is equivalent to: trapz(de.val(:,1),de.val(:,2)). mean(de)- Returns the mean ofde.val. Ifde.valis scalar, simply returns this number. Ifde.valis a two-column matrix, returns the mean of the second column....
