tt_ones

PURPOSE ^

Tensor of all ones

SYNOPSIS ^

function [tt] = tt_ones(n,varargin)

DESCRIPTION ^

Tensor of all ones
   [TT]=TT_ONES(N,D), computes the d-dimensional TT-tensor of all ones 
   with mode size equal to N

   [TT]=TT_ONES(N), computes the TT-tensor of all ones with mode size 
   given in the vector N
