Documentation

EinTensorExpression is a base class for tensor expressions, involving EinTensorExpressionAtoms, EinSummationTensorExpression, and EinProductTensorExpression objects.

The eval(), getMultiIndices() and contains shall be implemented by inheritors.

EinTensorExpression is parametrized over T. T is requested to have operators + and *.

operator T() const

virtual ~EinTensorExpression()

virtual T eval() const

virtual void getMultiIndices(EinMultiIndex &up, EinMultiIndex &lo) const

virtual bool contains(const EinTensor<T> *t) const

EinTensorExpression()

EinTensorExpression(const EinTensorExpression<T>&)
