Single particle scattering

Calculate the single particle scattering orbit and draw the animation under the given potential field.

Calculate the single particle scattering orbit and draw the animation under the given potential field.

main.m : input the expression V of the potential field, the particle velocity vi at infinity, and the aiming distance d (the distance from the center of the potential field to the asymptote).

calculate_r.m : Use ode45 to calculate the radius of the particle relative to the center of the potential field in the polar coordinate system.

calculate_phi.m : Calculate the azimuth angle of the particle relative to the center of the potential field in the polar coordinate system.

animation_plot_fun.m: Draw particle motion animation, if_export_gif=1, output demonstration animation in gif format.
