Can anyone please debug the error

My function is as follows

function F = myobjfun(x,y) syms i x y k F = symsum(((y(3).*x(i).*log(1+x(i))/symsum(x(k),k,0,9)-(y(2).*x(i))),i,0,9); end

when i am passing x=[1,2,....10], y=[0.5,0.5]

I am getting the following error

Error using mupadmex Error in MuPAD command: Index exceeds matrix dimensions.

Error in sym/subsref (line 1580) B = mupadmex('symobj::subsref',A.s,inds{:});

Error in myobjfun (line 4) F = symsum(((y(3).*x(i).*log(1+x(i)))-(y(2).*x(i))),i,0,9);

You had made some errors:

• symsum is a symbolic command for symbolic variables.

   symsum(x(k),k,0,9) ->  sum(x)

• in matlab, don't exist the zero index, the first index is one.
• you had miss one parenthesis some where.
• the argument y, only have 2 elements.

   y(3) ->  y(1)

• i think that you're confusing matlab script with another symbolic language like mathematica, cause you don't need symbolic toolbox.

function F = myobjfun(x,y)
n = numel(x);
i = 1;
F = y(1).*x(i).*log(1+x(i))/sum(x) - y(2).*x(i);
for i=2:n,
   F = F + y(1).*x(i).*log(1+x(i))/sum(x) - y(2).*x(i);
end
