Exponential Convergence for Numerical Solution of Integral Equations Using Radial Basis Functions

Figure 1

The horizontal axis is related to and the vertical axis shows the corresponding error values. It is perceived that the relation between and log (error) is linear. It confirms can affect error exponentially. We emphasize the spectral accuracy is the most important feature of the method. The relevant data is presented in Tables 1, 2, and 3.
