In this paper, we solve the Burgers' equation by pseudospectral method. This equation
is one-dimensional quasilinear partial differential equation. To reduce round-off
error of pseudospectral method we use Darvishi's preconditioning. The numerical
results obtained by this method, for different values of viscosity, have been compared
with the exact solution. It was seen that they were in good agreement with each other,
because norm infinity of error is very small.
