摘要
In this paper, an algorithm how to determine the optimal base functions and it’snumber is presented in fitting curve with exponential function. The method avoidselecting initial value and getting local extremum in fitting curve with nonlinear leastsquare method (NLSM). Numerical results show that the algorithm is very effective infitting of curve with exponential function.
