linalg(deprecated)

  

vecpotent

  

compute the vector potential

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

vecpotent(f, var, 'V')

Parameters

f

-

vector function of length three

var

-

list of three variables

V

-

name in which the vector potential is returned

Description

• 

Important: The linalg package has been deprecated. Use the superseding command VectorCalculus[VectorPotential], instead.

  

- For information on migrating linalg code to the new packages, see examples/LinearAlgebraMigration.

• 

The function vecpotent determines whether a given vector function has a vector potential, and determines that vector potential if it exists.

• 

The function returns true if the function f has a vector potential, and false if it does not.  The vector potential exists if and only if the divergence of f is zero.

• 

If a vector potential for f exists, it will be assigned to the name given in the third argument V.  If vecpotent returns true, then V will be assigned a vector function such that curl V = f.

• 

The command with(linalg,vecpotent) allows the use of the abbreviated form of this command.
