In Figure 3,local polynomial smoother approximates analytical solution in Example 2 with parameters n=51,p=3,h=0.1,which is much more efficient and accurate.We also solve LPS under different order p=3,4 by fixing bandwidth h=0.2,n=51 for Example 2 in Figure 4.We can find the magnitude of errors decreases to between 10 to the power of-11 and 10 to the power of-13.Table 2 gives the comparison results on the absolute errors derived from the LPS method,pseudospectral method and Adams-Bashforth method at point ti=0.0:0.2:1.0 in Example 2,which shows that the LPS method proposed is most efficient and most accurate than other two methods.
