f=@(x1,x2) 2*x1^2+x2^2+2*x1*x2+x1-x2;
x1=0; x2=1;
X=[x1;x2];
How to evaluate function using vector X..?
f(X) is not working.

To evaluate it with a matrix input, each of the variables has to refer to a column (or row) of that matrix.
You have defined ‘X’ as a column vector, so this syntax for your function works with it:
f=@(x) 2*x(1,:).^2 + x(2,:).^2 + 2*x(1,:).*x(2,:) + x(1,:) - x(2,:);
x1=0; x2=1;
X=[x1;x2];
Result_1 = f(X)
X2 = randi(9, 2, 5); % Create Input Data Matrix
Result_2 = f(X2)
