A rank-m tensor is a mathematical object that represents
rank-0 Tensor: represents a single real number and is usually called a scalar. Examples of rank-0 tensors (scalars) are temperature, density etc.
rank-1 Tensor: represents N real numbers and is usually called vectors. Examples of rank-1 tensor (vector) are velocity, force, etc.
rank-2 Tensor: represents N^2 real numbers that can be arranged as a
