length

Return number of elements in geographic or planar vector

Syntax

n = length(v)

Description

n = length(v) returns the number of elements contained in the geographic or planar vector v.

Examples

Find Length of Geopoint Vector

Create a geopoint vector and find its length.

load coastlines
p = geopoint(coastlat, coastlon);
length(p)

ans = 
9865

length(coastlat)

ans = 
9865

Input Arguments

v — Geographic or planar vector

geopoint, geoshape, mappoint, or mapshape object

Geographic or planar vector, specified as a geopoint, geoshape, mappoint, or mapshape object.

Output Arguments

n — Number of elements

nonnegative integer scalar

Number of elements in vector v, returned as a nonnegative integer scalar. The result is equivalent to size(v,1).
