Rybicki Press algorithm
text:
The Rybicki–Press algorithm is a fast algorithm for inverting a matrix whose entries are given by A = exp , where a ∈ R and where the t i are sorted in order. The key observation behind the Rybicki-Press observation is that the matrix inverse of such a matrix is always a tridiagonal matrix, and tridiagonal systems of equations can be solved efficiently. It is a computational optimization of a general set of statistical methods developed to determine whether two noisy, irregularly sampled data
