Compute divergence of vector field – MATLAB divergence
The Helmholtz decomposition can also be generalized by reducing the regularity assumptions the need for the existence of strong derivatives. A terminology often used in physics refers to the curl-free component of a vector field as the longitudinal component and the divergence-free component as the transverse component.
The arrays X and Ywhich define the coordinates for U and Vmust be monotonic, but do not need to be uniformly spaced. By William Woolsey Johnson.

Thanks to the divergence theorem the equation can be rewritten as. The term “Helmholtz theorem” can also refer to the following. The American Mathematical Monthly.
Trial Software Product Updates. Midwestern Universities Research Association, Translated by Mouseover text to see original.
Use color to indicate divergence. Founded on the Method of Rates Or Fluxions. Chelsea Publishing Company, Then decompose this field, at each point kinto two components, one of which points longitudinally, i. MathWorks does not warrant, and disclaims all liability for, the accuracy, suitability, or fitness for purpose of the translation. In physics and mathematicsin the area of vector calculusHelmholtz’s theorem  also known as the fundamental theorem of vector calculus       states that any sufficiently smoothrapidly decaying vector field in three dimensions can be resolved into the sum of an irrotational curl -free vector field and a solenoidal divergence -free vector field; this is known as the Helmholtz decomposition or Helmholtz representation.
From Wikipedia, the free encyclopedia. It is named after Hermann von Helmholtz. This theorem is of great importance in electrostaticssince Maxwell’s equations for the electric and magnetic fields in the static case are of exactly this type. Then there exists a vector field F such that. By James Byrnie Shaw.

However, the compactness restriction in the usual formulation of the Hodge decomposition can be replaced by suitable decay assumptions at infinity on the differential forms involved, giving a proper generalization of the Helmholtz theorem.

In other words, a vector field can be constructed with both a specified divergence and a specified curl, and if it also vanishes at infinity, it is uniquely specified by its divergence and curl.
