In the conventional approach to the serial solution of the one-dimension diffusion equation using continuous space-discrete time (CSDT) techniques, there is a large amount of positive feedback in the resultant analog programming. For all practical purposes, the presence of this positive feedback makes the conventional analog method useless.
Continuous space-discrete time solution, heat equation, instability, integral equation, modified Neumann series, partial differential equation, variable coefficients.
