Skipping fzero error in a loop
显示 更早的评论
I am trying to solve an algabraic equation with two parameters that are varying in a loop. The basic form of the program is as follows:
nn=linspace(0.01,1,10);
aa=logspace(0,3,10);
inn=length(nn);
iaa=length(aa);
ss=1+1./nn;
for ii=1:inn
for jj=1:iaa
ii
jj
Y0=[0 1];
fun=@(Y) (1+Y)^ss(ii)-Y^ss(ii)-ss(ii)*aa(jj);
YY(ii,jj)=fzero(fun,Y0)
end
end
Now at some point at values of ii=2 & jj=7 the programs figures that a solution is not available, and stops. The error message reads: "The function values at the interval endpoints must differ in sign.", which understandably is due to the nature of the
Is there a way to get the program to keep running?

Yes!
Now I suppose you want to know how?
Define: ‘Y0=1’, not a vector of values. This gives you a matrix with many NaN values and many others with solutions outside ‘[0 1]’. You can convert these to NaN on your own later if you like, with:
YY(YY>1) = NaN;
The point is that the code completes and fills your matrix.
