Abstract: The density distributions of particle in various potential fields are simulated based on the quantum mechanics with Matlab using an exponential difference algorithm. It is found that the density distribution of particle changes obviously with the change of potential field and entrance mode of particle. The simulation can be widely used in various quantum mechanical problems.

Key words: potential field, quantum mechanics, Matlah
