Zhiqing Luo · Science Technology and Engineering · 2013
Based in the analysis of multi-quadric function,it is found that the value of the smooth factor should be in a perfect range for obtaining a higher fitting precision.If the value of smooth factor in the range,the fitting precision is good.The factor of the fitting precision is analyzed,then,the formula of the smooth factor is acquired. Through experiment texted,it's proved that the value of the smooth factor just in the range and the fitting precision is perfect.
