Create an AD-compatible array

Creates a fixed-size vector, matrix, or higher-dimensional array that is safe to use inside `rtmb_code()` when subsequent assignments may involve RTMB automatic-differentiation values. This is a safer alternative to `array(value, dim)` or `matrix(value, ...)` in model code.

Usage

rtmb_array(value = 0, dim, seed = NULL)

Arguments

value

Initial value. Usually a scalar such as `0`.

dim

Integer dimension vector.

seed

Optional AD value used to create the container. See `rtmb_vector()`.

Value

An AD-compatible array.
