Kruskal tensor with symktensor</h2><p>The <tt>symktensor</tt> format stores the vectors and weights of a symmetric Kruskal tensor decomposition. The vectors in the decomposition are collected as the columns of a matrix <tt>X</tt>, referred to as the factor matrix. The lambda vector, containing the (often optional) weights is input into the constructor as a column vector. The lambda vector and factor matrix are collectively referred to as the constituent parts in the declaration of a <tt>symktensor</tt>. For
