[Z, LAT, LON] = DTED_READ(FILENAME) returns elevation data (Z) in the specified DTED file as a regular data grid with elevations in meters. LAT and LON provide 1D arrays with latitudes and longitudes (in degrees) corresponding to columns and rows of the elevation grid.
DTED files usually follow specific filename and directory name format ending with for example with "\e003\n15.dt0". If file is in the proper format than additional verifications are performed to ensure correctness.

[Z, LAT, LON, HEADER] = DTED_READ(FILENAME) also returns HEADER struct with metadata fields extracted from the header. Only minimal amount of metadata is read.
