Examples
Determine Direction Cosine Matrix from Geodetic Latitude and Longitude
Determine the direction cosine matrix from the geodetic latitude and longitude.
lat = 45; lon = -122; dcm = dcmecef2ned(lat, lon)
dcm = 3×3
0.3747 0.5997 0.7071
0.8480 -0.5299 0
0.3747 0.5997 -0.7071
Determine Direction Cosine Matrix from Multiple Geodetic Latitudes and Longitudes
Determine the direction cosine matrix from multiple geodetic latitudes and longitudes.
lat = [45 37.5]; lon = [-122 -85]; dcm = dcmecef2ned(lat, lon)
dcm = dcm(:,:,1) = 0.3747 0.5997 0.7071 0.8480 -0.5299 0 0.3747 0.5997 -0.7071 dcm(:,:,2) = -0.0531 0.6064 0.7934 0.9962 0.0872 0 -0.0691 0.7903 -0.6088
Input Arguments
lat
— Geodetic latitude
M array
Geodetic latitude, specified as an M array in degrees. Latitude values can be any value. However, latitude values of +90 and -90 may return unexpected values because of singularity at the poles.
Data Types: double
lon
— Geodetic longitude
M array
Geodetic longitude, specified as a M array in degrees. Longitude values can be any value.
Data Types: double
Output Arguments
dcm
— Direction cosine matrix
3-by-3-by-M matrix
Direction cosine matrix, returned as a 3-by-3-by-M matrix, where
M is the number of orthogonal direction cosine matrices.
dcm
performs the coordinate transformation of a vector in
Earth-centered Earth-fixed (ECEF) axes into a vector in North-East-down (NED) axes.
Version History
Introduced in R2006b
