What is tensor vector?
These quantities are tensors (By the way, scalar is a tensor of zero rank). Vector is a first rank tensor. For example, the force or electric field are vectors. For the given coordinate system, vector is completely defined by their three components.

What is a Tensor Vector?
A tensor vector is a mathematical object that represents a vector in the context of tensor calculus. It is an important concept in physics and mathematics, particularly in the field of linear algebra. To understand tensor vectors, it is necessary to have a basic understanding of vectors, tensors, and tensor calculus.
Vectors:
A vector is a mathematical object that has both magnitude and direction. It can be represented by an ordered list of numbers, known as components, in a coordinate system. Vectors are commonly used to represent physical quantities such as displacement, velocity, and force.
Tensors:
Tensors are mathematical objects that generalize the concept of vectors and matrices. They can have multiple dimensions and can represent more complex relationships between quantities. Tensors have both magnitude and direction, and their components can vary with respect to different coordinate systems.
Tensor Calculus:
Tensor calculus is a branch of mathematics that deals with the differentiation and integration of tensors. It extends the principles of calculus to tensors, enabling the study of more complex mathematical objects. Tensor calculus plays a crucial role in fields such as physics, engineering, and computer science.
Tensor Vector:
A tensor vector is a specific type of tensor that represents a vector in a given coordinate system. It is a first-order tensor, meaning it has one contravariant index. The components of a tensor vector can be represented as a list of numbers, similar to a regular vector. However, these components may transform differently under coordinate transformations.
