dms2degrees - Convert degrees-minutes-seconds to degrees
Syntax
angleInDegrees = dms2degrees(DMS)
Description
angleInDegrees = dms2degrees(DMS) converts
angles from degree-minutes-seconds representation to values in degrees
which may include a fractional part (sometimes called "decimal
degrees"). DMS should be N-by-3 and real-valued,
with one row per angle. The output will be an N-by-1 column vector
whose kth element corresponds
to the kth row of DMS.
The first column of DMS contains the "degrees"
element and should be integer-valued. The second column contains the
"minutes" element and should be integer-valued. The
third column contains the "seconds" element and may
have a fractional part. For an angle that is positive (north latitude
or east longitude) or equal to zero, all elements in the row need
to be nonnegative. For a negative angle (south latitude or west longitude),
the first nonzero element in the row should be negative and the remaining
values should be positive. Thus, for an input row with value [D
M S], with integer-valued D and M,
and real D, M, and S,
the output value will be
SGN * (abs(D) + abs(M)/60 + abs(S)/3600)
where SGN is 1 if D, M,
and S are all nonnegative and -1 if the first nonzero
element of [D M S] is negative (an error results
if a nonzero element is followed by a negative element). Any fractional
parts in the first (degrees) and second (minutes) columns of DMS are
ignored. An error results unless the absolute values of all elements
in the second (minutes) and third (seconds) columns are less than
60.
