How to initialise std shared pointer for valarray

Question

I am trying to initialise a shared pointer of std::valarray<double>, my code is

class foo {

    public:

        foo();

    private:

        std::shared_ptr<std::valarray<double>> meanValues;
};

In the constructor, I would like to fill up meanValues

foo::foo() {

    this->meanValues = std::make_shared<std::valarray<double>>(2);
}

How do I fill up meanValues to have two values {1.2, 4.5}

You can explicitly specify the std::initializer_list:

foo::foo()
{
    this->meanValues = std::make_shared<std::valarray<double>>(std::initializer_list<double>{1.2, 4.5});
}
