Question

运行matlab时出现的错误提示，这是什么原因造成的。

Failure in initial user-supplied objective function evaluation. FMINCON cannot continue.
Failure in initial call to fmincon with user-supplied problem structure.

Answer 1

fmincon调用的方式错了，给你个参考

% Set up fmincon's options
x0 = [0 0];
lb = [-90 -90];
ub = [90 90];
% Set up fmincon
[x, fval] = fmincon(@(x) myfun(x),x0,[],[],[],[],lb,ub)
