The tridiagonal matrix algorithm (TDMA), also known as the Thomas algorithm, is a simplified form of Gaussian elimination that can be used to solve tridiagonal systems of equations. A tridiagonal system may be written as where and . In matrix form, this system is written as paraheat_pwc_1d, a MATLAB program which sets up and solves a parameterized steady heat equation in a 1D spatial domain, with a piecewise constant diffusivity. paraheat_pwc_1d_test paraheat_pwc_plot , a MATLAB program which use radial basis functions (RBF) to reconstruct the finite element solution sampled by paraheat_pwc().
