how to Write a code that returns the objective function (scalar) as the first output The gradient (vector) as the second output and the out put and also the out put should depend on the number of the variable

basically i want evaluate an objective function of this kind

F(x,t)=[exp(sqrt(x1^2+x2^2+t^2)-1),0.5(x1+x2+(sqrt(x1-x2)^2+t^2),.......)

up to n-times where n is length of x usually give as 2-dim 3-dim to n-dim, also i need the code to do the evaluation element wise
