Fzero matlab用法
WebDescripción. x = fzero (fun,x0) trata de encontrar un punto x donde fun (x) = 0. Esta solución es donde fun (x) cambia de signo: fzero no puede encontrar una raíz de una función como x^2. x = fzero (fun,x0,options) utiliza options para modificar el proceso de resolución. x = fzero (problem) resuelve un problema de búsqueda de raíz que ...
