Conversely, the smallestabs option uses the inverse of a, and therefore the inverse of the eigenvalues of a, which have a much larger gap and are therefore easier to compute. Since inv performs the matrix inversion using floatingpoint computations, in practice yx is close to.

In chapter 4, an eigenfrequency study is carried out for various types of rooms, and the influence of different wall and ceiling forms is examined.
