The numerical simulation of the 2 soliton solution of the complex SP equation. The graphs show the imaginary part of u of the complex SP equation. The points shows the numerical values, and the continuous curve shows the exact value, and the points on the bottom of graphs show the distribution of mesh grid points. p1=0.5+i, p2=0.8+2i, a1=e−6, a2=e4.
