MATLAB: Undefined Function error (Undefined)

errorfunctionundefined

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 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
