A unit vector is a vector of length equal to 1. When we use a unit vector to describe a spatial direction, we call it a direction vector. In a Cartesian coordinate system, the three unit vectors that form the basis of the 3D space are: (1, 0, 0) — Describes the x-direction; ...

We now define the math operations for vectors. The operations we can perform on vectors ~u = (u1, u2, u3) and ~v = (v1, v2, v3) are: addition, subtraction, scaling, norm (length), dot product, and cross product: The dot product and the cross product of two vectors can also be...
of any order into lower-dimension unitary matrices, which ensures the existence of an optical realization through two fundamental building blocks that are beam splitters (couplers) and phase shifters. Despite its generality, this method uses a pyramid-shaped array of Mach-Zehnder interferometers (MZI...
Molecular dynamics (MD) is an indispensable atomistic-scale computational tool widely-used in various disciplines. In the past decades, nearly all ab initio MD and machine-learning MD have been based on the general-purpose central/graphics processing uni
spk_Y [D x N] spike feature vectors (in D dimensions) for N spikes. spk_t [N] spike times. These are used to determine which time frame each spike belongs to, and all of these must fall within the range covered by mu_t. You can use whatever time units you like, as long as ...
Implemented using :alist* plus a check of the list length, which could be incorrect if the criterion lists duplicate keys. Usage: (:alist KEY-TEST-FN VALUE-TEST-FN (KEY VALUE) ... (KEY VALUE)) Criteria for vectors Criterion across The :across criterion is like :seq, but for a ...
1.A method for operating a metering unit for an ambulatory infusion device, comprising:a) providing a dosing unit and a driving unit;b) coupling a plunger of the dosing unit, the plunger being located, at least in part, in a metering cavity of a movable member of the metering unit and...
