A question on minimizing a composition function with multiple variables how to min g(f(x), k(x),w(x))?

hi, all my main question is whether i can have g=@x (f(x),y(x),k(x)) solved? where f(x),y(x),k(x) being a function of x(1),x(2),x(3),x(4),x(5)

 here is the question, if i make g only compose one of the function above it is working. with g=@x expression with only variable x

However, if i want g to be a function of f, y, k, w, i would see error on "too many input arguments".

Any ideas? Or how to use it properly?

It's just the use of round parentheses to gather the variables. Is this what you're trying to do?

f = @(x) x;
k = @(x) x.^2;
w = @(x) x.^3;
g = @(x) [f(x) k(x) w(x)];

x = (1:5)';
g(x)
