Error inside of function using feval on user-provided polynomial
显示 更早的评论
Hi all, I am having an issue with my code and I can't figure it out for the life of me. Here's my code:
function [l,r,nf] = bisect(fname,a,b,tol)
if(a == b)
if(feval(fname,a) == 0)
l = a;
r = l;
nf = 0;
return;
else
l = NaN;
r = l;
nf = -1;
return;
end
end
The error message states:
Error using feval
Function to evaluate must be represented as a string scalar, character vector, or function_handle object.
Error in bisect (line 26)
if(feval(fname,a) == 0).
Can anyone point me in the right direction? Help would be so much appreciated.

What are you passing to bisect()?

Can you specify what input arguments are passed to that function with syntax ?
