Integration of numerical data
古いコメントを表示
I have a set of numerical data stored in a vector D, and a second vector of positions z, of equal length.
If i wish to calculate the integral shown in the picture, how would this be done?

Multiply the two vectors. Then call trapz.

For vectors of data, the best option would be the trapz (link) or the related cumtrapz functions, depending on the result you want.

I have not so regular data (x and y are returned from ode45).
How can I visualize the rectangles under the curve to see how good trapz is doing?
