Re: [eigen] TensorMap in 3.3-rc1

[Benoit Steiner <bsteiner@xxxxxxxxxx>]

You need to write:

  double dat[6];

  Eigen::TensorMap<Eigen::Tensor<double>, 2> Tm(dat, 2, 3);

I tried a very simple test of TensorMap in MS VS 2013:

  double dat[6];

  Eigen::TensorMap<double, 2> Tm(dat, 2, 3);

and get a blizzard of error messages, the first several are pasted below.

I was able to test other parts of the Tensor module with no

problems. I'd be happy to try more experiments or provide more info.

Thanks,

Bill
