| May 21, 2015 at 12:29 | comment | added | user12876 | Hi Histograms, I'm only concerned with building a large array with numerical entries. Right now the slowest part by far is the line: tensor = Table[dotprod, ##] & @@ tablelimits; So in the absence of a better way of doing the full calculation, really my question boils down to finding a faster way of constructing this Table with numerical entries. | |

Have you looked at the Tensor functions: reference.wolfram.com/language/guide/SymbolicTensors.html ? I'm not sure what general tensor you're trying to build but multiple calls to KroneckerProduct ,TensorProduct and Outer might speed things up.
