Undefined Function error (Undefined)

Hi there,

It is my function:

function [y, cons] = TMS_CONSTR_objfun(x)
y = [0 0];
cons = [];
x(1:10)=1;
d(1:10)=0;
sp(1:10)=0;
y(1)=sum(x(1:10));
for h=1:10
    d(h)=x(h)*xe(h);
    sp(h)=x(h)*ve(h);
end
dd=d(d~=0);
spp=sp(sp~=0);
n=length(dd);
for j=2:n-1 y(2)=abs(((dd(1)+dd(2))/(2*spp(1)))+9.7-((x(n)+x(n-1))/(2*spp(n))+ sum((x(j+1)-x(j-1))/(2*spp(j))))); end

xe and ve are variables that imported from excel. I keep receive this error:

Undefined function 'xe' for input arguments of type 'double'. and

Undefined function or variable 'x'.

Please help. Thanks

xe and ve are not defined anywhere in this function. If you import them in another function, you have to pass them to this function. for x: how do you call this function?

xe is used inside your function and can not be recognized even if it exist in the Matlab workspace. You need to declare it as input argument
