Syntax

fieldsCustom(field,points)
fieldsCustom(field,points,scalefield)
qobj = fieldsCustom(___)
fieldsCustom(axeshandle,___)

Description

fieldsCustom(field,points) plots electric or magnetic field vectors, fields, at specified points in space, points, in the current axes.

example

fieldsCustom(field,points,scalefield) scales the field arrows by a scalar value, scalefield.

example

qobj = fieldsCustom(___) returns the quiver object, using either of the previous syntaxes.

fieldsCustom(axeshandle,___) plots into the axes specified by axeshandle instead of the current axes.

fieldsCustom(H,p)

Figure contains an axes object. The axes object with xlabel X, ylabel Y contains an object of type quiver.

Scale the magnetic field arrows by a factor of 2.

figure
fieldsCustom(H,p,2)

Figure contains an axes object. The axes object with xlabel X, ylabel Y contains an object of type quiver.

Input Arguments

collapse all

Complex electric field strength vector in V/m or magnetic field strength vector in A/m at field points, specified as a 3-by-p complex matrix. p is the number of points in space.

Data Types: double
Complex Number Support: Yes

Cartesian coordinates x, y, and z of field points, specified as a 3-by-p real matrix. p is the number of points in space.

Data Types: double

Axis handle, specified as an axes object.

Data Types: char

Value by which to scale the field arrows, specified as a scalar. A value of 2 doubles the relative length of the field arrows. A value of 0.5 halves the length of the field arrows. A value of 0 plots the field arrows without automatic scaling.

Example: 2

Data Types: double

Output Arguments

collapse all

Electric or magnetic field plot, returned as quiver object.
