The tensor order axis of a quantity's character

Synopsis

Declared in <mp‐units/framework/quantity_character.h>

enum class quantity_tensor_order : int8_t;

Description

A quantity's character splits into two orthogonal axes: its tensor order (scalar, vector, tensor) and its numeric field (real, complex). The enumerators are declared in increasing rank so that the underlying comparison orders them (scalar < vector < tensor, real < complex).

Description

scalar

A quantity with magnitude but no direction.

vector

A quantity with both magnitude and direction.

tensor

A quantity that additionally carries orientation (e.g. the Cauchy stress tensor).
