Root finding problem
...o. :-( Again, what I want is to find the root of the above-mentioned function, for arbitrary values of x, a, and lambda, and just specifying one value for u as a starting guess. Could anyone please give me a suggestion of how to do that? Thanks in advance. In MATLAB I do the following: function u=tukeysolve(a,lambda,xgrid) u=zeros(length(xgrid),1); old=0.001; % just a guess for i=1:length(xgrid) x=xgrid(i); u(i) = fsolve(@tuki,old,optimset('Display','Off','tolf',5e-8),x,a,lambda); old=u(i); % use previous value as new start value end function f=tuki(u,x,a,lambda) f = x -...
