针对你提出的问题“invalid matlab indexing or symbolic function definition. symbolic function arguments must be symbolic variables and function body must be convertible to sym expression”,我们可以从以下几个方面进行分析和解答: 检查MATLAB代码中的索引使用是否正确: 在MATLAB中,索引必须遵循MATLAB的索引规则。
Before runningfminsearch, convert your symbolic expression to a MATLAB function by usingmatlabFunction: myfun = matlabFunction(funfun,'Vars',{a}); a0 = [-1,1]; [x,fval,exitflag,output] = fminsearch(myfun,a0) When I ran this I got the following result: ...

I created a function [y1,y2,y3]=example(x1,x2,x3) where it solves a list of equation using symbolic toolbox (syms and solve). Then i evaluated the expression to get values (eval command). The output of the function is this evaluated value. This works well when i call it from comm...
Substitutions in Symbolic Expressions: You can substitute a symbolic variable with a numeric value by using the subs function. For example, evaluate the symbolic expression f at the point x = 1/3:syms x y f = 2*x^2 - 3*x + 1; subs(f, 1/3) ans = 2/9 f = x^2*y + 5*x*...
matlabFunctioncan generate a function handle from any symbolic expression. For example: syms x y r = sqrt(x^2 + y^2); ht = matlabFunction(tanh(r)) ht = function_handle with value: @(x,y)tanh(sqrt(x.^2+y.^2)) You can use this function handle to calculate numerically: ...
