Regularization of a discrete backward problem using coefficients of truncated Lagrange polynomials
We consider the problem of finding the initial temperature $u(x,0)$, from a countable set of measured values ${ u(x_j,1)}$. The problem is severely ill-posed and a regularization is in order. Using the Hermite polynomials and coefficients of truncated Lagrange polynomials, we shall change the proble...
