Hello I have this tridiagonal matrix.
where r = 1/x, g= 1/x^2, s=ln(x)/x^2 and n represents the size.
I'm trying to solve this matrix in Matlab using the Thomas algorithm. I have found some online resources however they dont tend to deal with when n becomes very large, I need to solve matrices that are maybe 20 x 20 or 40 x 40 and so on.
Sorry for this vague description, I'm quite new to using matlab.
