aer2enu

Local spherical AER to local Cartesian ENU

Syntax

  • [xEast,yNorth,zUp] = aer2enu(az,elev,slantRange)
  • [___] = aer2enu(___,angleUnit)

Description

[xEast,yNorth,zUp] = aer2enu(az,elev,slantRange) returns coordinates in a local east-north-up (ENU) Cartesian system corresponding to coordinates az, elev, slantRange in a local spherical system having the same origin. Any of the three numerical input arguments can be scalar, even when the others are nonscalar; but all nonscalar numeric arguments must match in size.

[___] = aer2enu(___,angleUnit) adds angleUnit which specifies the units of inputs az and elev..

Input Arguments

collapse all

Azimuth angles in the local spherical system, specified as a scalar, vector, matrix, or N-D array. Azimuths are measured clockwise from north. Values must be in units that match the input argument angleUnit, if supplied, and in degrees, otherwise.

Data Types: single | double

Elevation angles in the local spherical system, specified as a scalar, vector, matrix, or N-D array. Elevations are with respect to a plane perpendicular to the spheroid surface normal. Values must be in units that match the input argument angleUnit, if supplied, and in degrees, otherwise.

Data Types: single | double

Distances from origin in the local spherical system, returned as a scalar, vector, matrix, or N-D array. The straight-line, 3-D Cartesian distance is used. Units are determined by the LengthUnit property of the spheroid input.

Data Types: single | double

Units of angles, specified as ‘degrees' (default), or 'radians'.

Data Types: char

Output Arguments

collapse all

x-coordinates of one or more points in the local ENU system, returned as a scalar value, vector, matrix, or N-D array.

y-coordinates of one or more points in the local ENU system, returned as a scalar value, vector, matrix, or N-D array.

z-coordinates of one or more points in the local ENU system, returned as a scalar value, vector, matrix, or N-D array.
