Implementation of summation Matlab

Hello! I have given a function , where a is a vector with n(n between 1 and 10) varaibles, e is the Eulerian number and x is a vector with 10 random values. I should now compute the following sum: , where y is also a vector with 10 random values. Can anyone help me to implement that please?
I have written this:
t=symsum((transpose(a(:)).*cos((1:n).*X(j)*e)-Y(j)).^2,j,1,11)
but it says this error: Array indices must be positive integers or logical values. The error is because one variable in my vector a is negative.

Try this
a = 1:10;
x = rand(1, 10);
y = rand(1, 10);
e = 1;
z = sum(a(:).*cos((1:numel(a)).'*x(:).'*e)-y(:).', 'all')
