f3_3.m

利用幂法反幂法等进行程序运算,可以获得各种适用结果.

function f3_3(p,x)
[curve, goodness] = fit(K,L,Q,'pchipinterp');
curve = fit(K,L,Q,'exp1','Startpoint',p0)
% Q=p(1)*K.^p(2)&L.^p(3);
% 
%     fits a cubic interpolating spline through xdata and ydata.
%        
%     fits the 3rd equation in the curve fitting library of rational functions,
%     overriding the starting point to be p0.
