A Waring decomposition of a (homogeneous) polynomial f is a minimal sum ofpowers of linear forms expressing f. Under certain conditions, such adecomposition is unique. We discuss some algorithms to compute the Waringdecomposition, which are linked to the equation of certain secant varieties andto eigenvectors of tensors. In particular we explicitly decompose a generalcubic polynomial in three variables as the sum of five cubes (SylvesterPentahedral Theorem).
