distance
Distance between sites
Description
returns the distance with additional options specified by name-value
arguments.d
= distance(___,Name=Value
)
Examples
Distance Between Transmitter and Receiver Site
Create a transmitter site and a receiver site.
tx = txsite(Name="MathWorks",Latitude=42.3001,Longitude=-71.3504); rx = rxsite(Name="Fenway Park",Latitude=42.3467,Longitude=-71.0972);
Get the Euclidean distance in m between the sites.
dme = distance(tx,rx)
dme = 2.1504e+04
Convert the Euclidean distance to km.
dkm = dme / 1000
dkm = 21.5037
Get the great circle distance in m between the sites.
dmg = distance(tx,rx,"greatcircle")
dmg = 2.1451e+04
Input Arguments
path
— Measurement path type
"euclidean"
| "greatcircle"
Measurement path type, specified as one of the following:
"euclidean"
— Use the shortest path through space that connects the antenna center positions of the sites."greatcircle"
— Use the shortest path on the surface of the earth that connects the latitude and longitude locations of the sites. This path uses a spherical Earth model.
Data Types: char
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Example: d = distance(site1,site2,Map="myfile.stl")
specifies the
map as an STL file.
Before R2021a, use commas to separate each name and value, and enclose
Name
in quotes.
Example: d = distance(site1,site2,"Map","myfile.stl")
specifies
the map as an STL file.
Map
— Map for visualization or surface data
siteviewer
object | triangulation
object | string scalar | character vector
Map for visualization or surface data, specified as a siteviewer
object, a triangulation
object, a string scalar, or a character vector.
Valid and default values depend on the coordinate system.
Coordinate System | Valid map values | Default map value |
---|---|---|
"geographic" |
|
|
"cartesian" |
|

In most cases, if you specify this argument as a value other than a siteviewer
or
"none"
, then you must also specify an output argument.
