delaunayTriangulation Error: Inf and NaN are not permitted

Hi everybody,

i've a problem using delaunayTriangulation, i use it many times and it works fine but with a specific data vector x, y and z (in column) it generates an error:

Error using delaunayTriangulation
The coordinates of the input points must be finite values; Inf and NaN are not permitted.

And what i invoke is:

DTD=delaunayTriangulation(xD,yD,zD);

The problem is that in my vectors there aren't values equals to Inf or NaN, they are fine. I don't understand why returns this error.

Let us check the data......attach your (x,y,z) values...

Please try following command with the attached workspace file:

[X,Y] = voronoi(xo1,yo1)

which will give the error "Error using delaunay The coordinates of the input points must be finite values; Inf and NaN are not permitted.

Error in voronoi (line 89) tri = delaunay(x,y);"
