An Introduction to Tensors for Students of Physics and ~ Example: Force (a vector) equals mass (a scalar) times acceleration (a vector): f(nt) = m(kg) a(m/s2) where the force and the acceleration share a common direction. Introducing Tensors: Magnetic Permeability and Material Stress We have just seen that vectors can be multiplied by scalars to produce new vectors with the same sense or direction. In general, we can specify a unit vector u, at any .
Kees Dullemond & Kasper Peeters - Heidelberg University ~ 1 The index notation Before we start with the main topic of this booklet, tensors, we will first introduce a new notation for vectors and matrices, and their algebraic manipulations: the index

Introduction to Tensor Calculus for General Relativity ~ Having defined vectors and one-forms we can now define tensors. A tensor of rank (m,n), also called a (m,n) tensor, is defined to be a scalar function of mone-forms and nvectors that is linear in all of its arguments. It follows at once that scalars are tensors of rank (0,0), vectors are tensors of rank (1,0) and one-forms are tensors of .
PART 1: INTRODUCTION TO TENSOR CALCULUS ~ When these numbers obey certain transformation laws they become examples of tensor elds. In general, scalar elds are referred to as tensor elds of rank or order zero whereas vector elds are called tensor elds of rank or order one. Closely associated with tensor calculus is the indicial or index notation. In section 1 the indicial notation is de ned and illustrated. We also de ne and .
Vector Analysis - UCCS ~ The vector A is readily written in terms of the cartesian unit vectors xO, yO, and zO A DxOA xCyOA yCzOA z In linear algebra xO, yO, and zOare known as basis vectors, each having unit length, i.e., jxOjand mutually orthogonal Also, the length of A is AD q A2 x CA2 y CA2 z and the unit vector in the A direction is aOD A A D xOA xCyOA yCzOA z q A2 x CA2 y CA2 z 3-3. CHAPTER 3. VECTOR ANALYSIS (a .
PROGRAMMING OF FINITE DIFFERENCE METHODS IN MATLAB ~ PROGRAMMING OF FINITE DIFFERENCE METHODS IN MATLAB LONG CHEN We discuss efficient ways of implementing finite difference methods for solving the Poisson equation on rectangular domains in two and three dimensions. The key is the ma-trix indexing instead of the traditional linear indexing. With such an indexing system, we will introduce a matrix-free and a tensor product matrix implementation .
Rotation matrix for rotations around x-axis - MATLAB rotx ~ This example illustrates a basic property: the inverse rotation matrix is the transpose of the original. Rotation matrices satisfy A’A = 1, and consequently det(A) = 1. Under rotations, vector lengths are preserved as well as the angles between vectors. We can think of rotations in another way.
Cross product - MATLAB cross ~ If A and B are vectors, then they must have a length of 3.. If A and B are matrices or multidimensional arrays, then they must have the same size. In this case, the cross function treats A and B as collections of three-element vectors. The function calculates the cross product of corresponding vectors along the first array dimension whose size equals 3.

Lecture 3: Coordinate Systems and Transformations ~ Similar to 3D vector coordinates, we suppose now that a and b are the homogeneous representations of the same point or vector with respect to the two frames. Then aT 0 B @ v1 v2 v3 P0 1 C A = bT 0 B @ u1 u2 u3 Q0 1 C A = bTM 0 B @ v1 v2 v3 P0 1 C A; which implies that a= MTb and b= (MT) 1a: 5.

Vectors and Vector Spaces - Texas A&M University ~ Vectors and Vector Spaces 1.1 Vector Spaces Underlying every vector space (to be defined shortly) is a scalar field F. Examples of scalar fields are the real and the complex numbers R := real numbers C := complex numbers. These are the only fields we use here. Definition 1.1.1. A vector space V is a collection of objects with a (vector)
Quaternions and spatial rotation - Wikipedia ~ Unit quaternions, also known as versors, provide a convenient mathematical notation for representing space orientations and rotations of objects in three dimensions. Compared to Euler angles they are simpler to compose and avoid the problem of gimbal lock.Compared to rotation matrices they are more compact, more numerically stable, and more efficient.

(1, π/2, 1) 7 EX 4 Make the required change in the given equation. a) x2 - y2 = 25 to cylindrical coordinates. b) x2 + y2 - z2 = 1 to spherical coordinates. c) ρ = 2cos φ to cylindrical coordinates. 8 EX 4 Make the required change in the given equation (continued). d) x + y + z = 1 to .
Don’t Get Lost in Deep Space: Understanding Quaternions ~ I arbitrarily chose the z-y-x transformation matrix to work with in the examples below. Above is a transformation matrix that rotates z-y-x around α, β, γ . Gimbal lock becomes mathematically apparent in our example matrix when $$\beta=\frac{\pi}{2}$$ is substituted into a z-y-x transformation matrix (other transformation matrices fail with different conditions). As the angle $$\beta \to .
Covariance and contravariance of vectors - Wikipedia ~ Examples of vectors with contravariant components include the position of an object relative to an observer, . The duality between covariance and contravariance intervenes whenever a vector or tensor quantity is represented by its components, although modern differential geometry uses more sophisticated index-free methods to represent tensors. In tensor analysis, a covariant vector varies .

torch.norm — PyTorch 1.7.0 documentation ~ If the input tensor has more than two dimensions, the vector norm will be applied to last dimension. keepdim (bool, optional) – whether the output tensors have dim retained or not. Ignored if dim = None and out = None. Default: False. out (Tensor, optional) – the output tensor. Ignored if dim = None and out = None.
Vectors, Matrices and Coordinate Transformations ~ Examples of physical vectors are forces, moments, and velocities. Geometrically, a vector can be represented as arrows. The length of the arrow represents its magnitude. Unless indicated otherwise, we shall assume that parallel translation does not change a vector, and we shall call the vectors satisfying this property, free vectors. Thus, two vectors are equal if and only if they are parallel .

python - Rotation of 3D vector? - Stack Overflow ~ Quaternion Theory: A quaternion is a number with one real and 3 imaginary dimensions usually written as q = w + xi + yj + zk where 'i', 'j', 'k' are imaginary dimensions. Just as a unit complex number 'c' can represent all 2d rotations by c=exp(i * theta) , a unit quaternion 'q' can represent all 3d rotations by q=exp(p) , where 'p' is a pure imaginary quaternion set by your axis and angle.
