Details:

Hi all,

When writing polygons to a shapefile with shapewrite, only a .shp file is
produced (no .shx or .dbf files). The .shp file seems to be corrupt and cannot
be opened with Quantum GIS (2.14.4) or read with ogrinfo. However, it can be
opened with shaperead.

Example:



s = struct;
j = 1;
s(j).Geometry = 'Polygon';
s(j).X = [1 2 2 1 1];
s(j).Y = [2 2 1 1 2];
s(j).BoundingBox = [1 1; 2 2];
s(j).Name = 'att1';

j = 2;
s(j).Geometry = 'Polygon';
s(j).X = [2 3 3 2 2];
s(j).Y = [3 3 2 2 3];
s(j).BoundingBox = [2 3; 2 3];
s(j).Name = 'att2';

shapewrite(s, 'test.shp');        
I = shaperead('test.shp');
