polysplit

Extract segments of NaN-delimited polygon vectors to cell arrays.

Syntax

• [latcells,loncells] = polysplit(lat,lon)
  

Description

[latcells,loncells] = polysplit(lat,lon) returns the NaN-delimited segments of the vectors lat and lon as cell arrays. Each element of the cell array contains one segment.

Example

• lat = [1 2 3 NaN 4 NaN 5 6 7 8 9]';
  lon = [9 8 7 NaN 6 NaN 5 4 3 2 1]';
  [latcells,loncells] = polysplit(lat,lon);
  
  [latcells' loncells']
  ans = 
      [3x1 double]    [3x1 double]
      [         4]    [         6]
      [5x1 double]    [5x1 double]
