the indirection via access could even be more workload, if any.

A vector is usually an array of many more than 2 elements of
some floating point type (i.e. not integer).

Performance issues are not relevant below a dozen elements.

If a parameter is an array (or a record),
the parameter is handed over by reference, not by value (i.e. copy)
by most compilers.
