I used the following functions to do an optimization problem and got the given error.
Could you please help me correct it.
Thanks
function v = funv(x)
%UNTITLED Summary of this function goes here
% Detailed explanation goes here
x1=x(1);
x2=x(2);
x3=x(3);
x4=x(4);
x5=x(5);
v = 46.149*x1+39.158*x2+19.834*x3+59.307*x4+35.526*x5;
end
function [c,ceq] = nlconst(x)
x1=x(1);
x2=x(2);
x3=x(3);
x4=x(4);
x5=x(5);
c=[];
ceq = x1+x2+x3+x4+x5-1;
end
clc;
clear;
A = [];
B = []; % the linear inequality constraints: A*X <= B
Aeq = [];
Beq = []; % the linear equality constraints: Aeq*X = B
LB = [];

x0 = [1, 1, 1, 1, 1]; % initial guess
[x,FVAL,EXITFLAG,OUTPUT,LAMBDA] = fmincon(@funv,x0,A,B,Aeq,Beq,LB,UB,@nlconst);

Please use
which -all nlconst
to check whether the nlconst.m you are getting is the one you expect.
