roducts. The symmetric structure means that each term in the summand is the outer product of a single vector with itself <img src="symktensor_doc_eq11319871188381094158.png" alt="$m$" style="width:11px;height:6px;"> times, where <img src="symktensor_doc_eq11319871188381094158.png" alt="$m$" style="width:11px;height:6px;"> is the number of modes of the decomposed tensor. This contrasts with a generic <a href="D1_ktensor_doc.html">Kruskal tensor</a>, where each summand is an outer product of m different vecto
