I continued to be puzzled with this problem of trying to convert a matrix using the shapewrite function. I have the following matrix...

A = [1,2,3,4];
lon = [-123.412482300000, -123.349197000000, -123.387645500000,-123.499196100000];
lat = [48.1177411000000,48.1170438000000,48.1850616000000,48.2661300000000];
[test2.Geometry] = deal('MultiPoint');
test2.id = A;
test2.lon = lon;
test2.lat = lat;
shapewrite(test2, 'test2');

when I run shapewrite I get the following error...

??? Error using ==> makedbfspec at 116
Attribute field id of geographic data structure S contains at least
one value that is not a scalar double.

Error in ==> shapewrite>parseInputs at 555
dbfspec = makedbfspec(S);

Error in ==> shapewrite at 77
[S, basename, dbfspec] = parseInputs(varargin{:});

If I eliminate id I still get the same error, now using the lon matrix and so on. I would really appreciate any help on this problem.

Thanks
Jon
