WebMar 11, 2013 · The core of the spline fitting function sets up the tridiagonal matrix and then uses it to solve the system of equations. The tridiagonal matrix is not represented as a matrix but rather three 1-d arrays, A, B, and C. Array A is the sub-diagonal, B is the diagonal, and C is the super-diagonal, to match the Wikipedia article names.
