WebIn the hierarchical Tucker format, the sparsity of the representation of a tensor is determined by the hierarchical rank (2) for subsets t from a dimension tree. If one puts the vectors x from (4) into the columns of a matrix (cf. Figure 2), then this is called a matricization of the tensor, and the rank of this matrix is the t-rank. high level generalisation meaning
