Hello Tom I would also favor ranking to be a runtime thing : that s also the choice made by xtensor and ArrayFire : https://xtensor.readthedocs.io/en/latest/index.html http://arrayfire.org/docs/gettingstarted.htm Now, are eigen::tensor imposing ranking to be template/compil-time for performance reasons ? Regards W.

The tensor module would be extremely useful for me if not for the limitation that the rank needs to be specified as compile-time template parameter. I am unable to use Eigen tensors for a generic n-dimensional application where I don’t know the tensor rank in advance. Please let me know if I’m missing something or if there are any future plans to change this? The boost tensor module, for example, has dynamic ranks and sizes: https://www.boost.org/doc/libs/develop/libs/numeric/ublas/doc/tensor.html Thanks, Tom ----------------- Tom Peterka Mathematics and Computer Science Division Argonne National Laboratory 9700 S.
