Tensor class was written in 1997 during my study of templates
(I found it examining my archives).
But I've not seen any such classes since. So I think it can be useful for students. The main reason I've wrote
it - for the convolution of tensors with any dimensionality. Also you can get and use any sub-tensor using
operator, for example can be written like
The demo project shows usage of tensors. You can:
Declare and init tensors (you should specify dimension and indexes range).
Tensor4 tt(3); // 4 - dimensions indexes can be 0-2 or "1"-"3"
Tensor2 t1(2); t1 = 1.0;
t1 = 2.0;
t1 = 3.0;
t1 = 4.0;
Convolute tensors - note that you can use different dimensions and one or more
constants in indices.
Use some arithmetical operations.
result3 = t1 + t2*2;
Print part or whole tensor.
Invert 4-dimension tensor with indexes (0,1).
ti = inverse(t);
To Do list
It can be easy to implement some more operations with tensors (different multiplication and so).
Please let me know, if you need some.
