Predicting instantaneous hourly and integrated daily direct and diffuse solar flux we can use Gaussian quadrature form. Valuable topic where we can see how to imply fast Gaussian quadrature based estimate for water vapor pathlenghts. So we can give hydrostatic equilibrium form of Gaussian quadrature which will represent the atmospheric density.

This serie of videos is enormously helpful, many thanks. Q: How does one choose the right formula to integrate a discrete function ? (In the video there are four "flavors" but we can find as many weight function as we want !) What kind of information on the function to be integrated should we have in order to perform such a choice ?

Difficult question. Sometimes the weight function is already inside the integral you need, when you are using special functions to solve pde's for example. For simple integration tasks, I would just use the MATLAB integrate function and not worry about it.

How do you get that the integral is found with W(x) by which method?

Q: Do we have a numerical approach for integrals involving generalized functions like Green's or Dirac delta? can orthogonal polynomials take the form of generalized function?

Hi professor Jeffrey, why do we assume that w1 = w2 = 1, and why do they have to be in symmetry?

I just made the algebra easier. You don't need to assume anything and just solve the equations.

So 3 points requires f(x) goes to polynomial 5, right?

I dont understand how this compares to kzbin.info/www/bejne/pIK9inWNd5uklc0 and kzbin.info/www/bejne/mXyuo3qobpiZbMU . There the weights only need to solve up to degreen n and the locations xi result from the polynomial division of f(x) by the order n polynomial.
