Function execute_vectorized 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn execute_vectorized(
    q: *mut CompilerResult,
    buf: *mut f64,
    n: usize,
) -> bool

Executes the compiled function n times (vectorized).

The calling function provides buf, which is a k x n matrix of doubles, where k is equal to the maximum(count_states, count_obs). The calling funciton fills the first count_states rows of buf. The result is returned in the first count_obs rows of buf.

Safety

it is the responsibility of the calling function to ensure
that q points to a valid CompilerResult.

In addition, buf should points to a valid matrix of correct size.
