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

x1=x(1);

v = 46.149*x1+39.158*x2+19.834*x3+59.307*x4+35.526*x5;

function [c,ceq] = nlconst(x)

x5=x(5);
c=[];
ceq = x1+x2+x3+x4+x5-1;

clc;

I have saved "funv" and "nlconst" as two different functions in the same directory i'm working on.
Is that what you are asking.
Thanks

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