help for the Gaussian Quadrature Integration

35 views (last 30 days)
Hi, all
I have a problem with using the Gaussian quadrature integration. I need to integrate time based- data, which is not function and a 3000*1 matrix data, The data comes out from the sensor with a time step of 0.625 sec. The trapezoid function was fine to provide the same size of matrix data for the output.
[output] = 0.625*cumtrapz(data)
However, In order to integrate 3000*1 matrix data, how can I use quadratic functions such as quadv, quadl, quadgk? Thank you in advance.

For discrete data, I recommend you check out this package. With it you can model your data then integrate the model.
