ismultipoint

Create an array of point shapes.

shape = geopointshape({39,[38 -30 29]},{-113,[-66 -31 42]});

Determine which elements of the array are multipoint shapes. The result indicates that the second element is a multipoint shape.

tf = ismultipoint(shape)

tf = 1x2 logical array

   0   1

Accessing the coordinate properties of a point shape array is not supported when the array contains multipoint shapes. You can determine whether an array contains multipoints by using the ismultipoint and any functions.

Create an array of geopointshape objects that represent locations in Boston, and determine which are multipoint shapes.

GT = readgeotable("boston_placenames.gpx");
shape = GT.Shape;
tf1 = ismultipoint(shape);

Use the any function to check whether the ismultipoint function detected any multipoint shapes in the array. A value of 0 indicates that the array does not contain multipoint shapes.

any(tf1,"all")

ans = logical
   0

Create a multipoint shape that represents three locations. Add the multipoint shape to the end of the array.

mp = geopointshape({[42.3625 42.3693 42.3477]},{[-71.0904 -71.0733 -71.0787]});
shape(end+1) = mp;

Verify that the array contains a multipoint shape.

tf2 = ismultipoint(shape);
any(tf2,"all")

ans = logical
