In this paper, we extend the idea of pseudo spectral method
to approximate solution of time fractional order three-dimensional heat
conduction equations on a cubic domain. We study shifted Jacobi polynomials and provide a simple scheme to approximate function of multi
variables in terms of these polynomials. We develop new operational matrices for arbitrary order integrations as well as for arbitrary order derivatives. Based on these new matrices, we develop simple technique to
obtain numerical solution of fractional order heat conduction equations.
The new scheme is simple and can be easily simulated with any computational software. We develop codes for our results using MatLab. The
results are displayed graphically.
