基于MATLAB的P－Ⅲ型频率曲线参数估算的优化
Optimization of P-Ⅲ Frequency Curve Parameters Based on MATLAB
摘要
Abstract
This paper optimized the parameter estimation of P-Ⅲfrequency curve by linear moment approach and the method of tentative cal-culation,based on least squares technique,was used to determine of the optimum frequency distribution curve,the process was programmed by Matlab. Finally,the designed hydrological variables values were output. And the optimized curve-fitting method was verified by comparing with the traditional visual adaptability estimation. The results show that the method can be effectively applied to the actual engineering.关键词
