WebSep 1, 2015 · There are several problems in your code: fzero tries to find a zero of the function supplied as first argument. You are supplying an equation, not a function. Matlab doesn't know what e is. Use exp.; The equation x+sin(x)==exp(x) doesn't seem to have real solutions. You probably mean x+sin(x)==-exp(x).; Taking these three things into account, … WebApr 14, 2024 · 17132426479说: 关于matlab最优化中fmincon函数的使用问题 - 塔楠回复: 主要是你的fconfun函数中的ln变量没办法赋值进去 你那样写肯定是不对的,fmincon函数 …

Esta solución es donde fun (x) cambia el signo: fzero no puede encontrar una raíz de una función como x^2. x = fzero (fun,x0,options) usa options para modificar el proceso de solución. x = fzero (problem) soluciona un problema de búsqueda de raíces ... riba sa kljunom
matlab中zero函数的用法 - CSDN文库
Webfzero ('fun',x) finds a zero of fun. fun is a string containing the name of a real-valued function of a single real variable. The value returned is near a point where fun changes sign, or NaN if the search fails. fzero ('fun',x) where x is a vector of length 2, assumes x is an interval where the sign of f (x (1)) differs from the sign of f (x ... WebOct 14, 2014 · fzero是一个数值搜索过程,依赖于函数特性,值的指定,以及matlab所能识别的最小步长。 如果想计算更准确,可以用符号函数求解0点。 符号函数不用关心具体的函数值,完全当做符号处理,所以,不存在上述不稳定因素。 riba sa najvise omega 3
