WebDec 18, 2024 · Even without a bracket, fzero will probably be faster and more stable than fsolve. Today, fsolve got lucky. Fsolve is a great tool, but it really is targeted at multi-variable problems, whereas fzero is written with the explicit idea of a one-variable problem in mind. As such, it is usually the better tool when you do have only a one variable ...

WebFeb 19, 2024 · The only flaw with fzero in this respect is if you do supply a bracket that does not have different signs at each end point, then it will fail, in a circumstance where fsolve MAY have succeeded. But had you given only one start point to fzero on the same problem, it too would often have worked, if a solution could be found.
