> Tensor<1, 3> b(); If you write this then you declare a function "b" returning a Tensor<1,3>. Declare the tensor without the parentheses: Tensor<1, 3> b; You can access individual elements of the tensor via operator[]: b[0] = 1; b[1] = 1; b[2] = 0; And you can do meaningful mathematical tensor operations. Including, scaling a tensor auto a = 5. * b; Adding two tensors together: auto c = a + b; Taking the inner product: auto k = a * b; etc. Best, Matthias -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
