Thanks for the word of advice.
I am trying to work it out with Spherepack, alongside, I also want to
work with this code so maybe I can even go on and compare both results
at some point.
I cannot apply the concept of collocation points in wikipedia to this
case. I have a data set with data at every longitude and latitude grid
point, thats my input array. Now the output array will be of order
lmax,lmax with coefficients for various l's and m's. So where does
collocation point come into picture? and what does cosine(theta) have
to do with it? I tried using cp as an array with cos(theta( values for
theta : 90 : -90 but getting NaN answers.
