and call fsolve to solve the system H=@(vet) fsolve(system,G); I keep getting the following error "Non scalar arrays of function handles are not allowed; use cell arrays instead"; I looked on the forum for other similar problems but I wasn't able to replicate the solutions since ...
When you are developing algorithms to solve technical computing problems, it is often useful to create functions on-the-fly so that you can customize them at run-time without having to define them in files beforehand. For example: You may want to create a function based on a ...
solve可以求符号解和数值解,而fzero只能求数值解,而且fzero必须至少2个argin,第一个为fun,第二个为指明在某个值的附近搜索根。具体参见Help。 3.1 solve solve不仅可以求出具体的一元方程的根,还可以求出符号表达式,但此时必须指明是针对哪个变量,而且solve的第一个argin eqn可以为符号表达式,也可以为function hand...
function F = myfun(x) F = sin(x); FUN can also be an anonymous function: x = fsolve(@(x) sin(3*x),[1 4],optimset('Display','off')) If FUN is parameterized, you can use anonymous functions to capture the problem-dependent parameters. Suppose you want to solve the system of no...
Note that this function has four input arguments and ouputs two arrays. Functions can be nested inside other functions. This is only useful if the nested function is only required by the main function. An example of this is shown in Section 3.11.1. Here the function solveq is not a gene...
Hi, Is it possible to write an anonymous function or a function handle that replicates the behavior of if-else statements? Consider the simple problem ifcondition a=b(x); else a=c(x); end it is possible to write the following function that will replicate that behavior ...

Solve system of nonlinear equations - MATLAB fsolve (mathworks.com) 求解代数方程的符号解。 S = solve(eqn1,eqn2,...,eqnM,var1,var2,...,varN) eqn 是符号表达式,可以是方程或不等式。vars是指定未知变量的符号变量表示。 fsolve 用来解决多个变量的非线性方程组。
