Module rest_tensors::tensor_basic_operation
source · [−]Traits
Trait definitions for tensor basic operations, mainly including
getting a (mutable) number, or a (mutable) slice from a defined tensor
Define for upper-formated tensors specifically, like
ERIFold4 with the indice of
[i,j,k,l], and
MatrixUpper with the indice of [i,j].
According to the upper-formated tensor definition, in principle, i=<j and k<=l.
WARNING: For efficiency, “uncheck” here means that we don’t check the index order during the tensor operations.
WARNING: As a result, a wrong index order could lead to a wrong operation.
