A tensor field is a mathematical construct that generalizes the concept of scalars and vectors to higher dimensions, allowing for the representation of more complex relationships in a variety of contexts, particularly in physics and engineering. ### Definition **Tensor**: A tensor is a multi-dimensional array of numerical values that transforms according to specific rules under a change of coordinates. Tensors can be classified based on their rank (or order): - **Scalar**: A tensor of rank 0 (single number).
