Hi, im newbie in vb.net and in general in programming.

I have a point cloud .txt , how can i introduce this in the matrix a?

Dim a(,) As Double = {{0, 1}, {0, 0}, {0, 2}}
Dim nx As Integer = 2
Dim ny As Integer = 0
Dim normtype As Integer = 2
Dim kdt As kdtree = New alglib.kdtree
Dim k As Integer
Dim x() As Double
Dim r(,) As Double = {}
alglib.kdtreebuild(a, nx, ny, normtype, kdt)
x = {2, 1}
k = alglib.kdtreequeryknn(kdt, x, 1)
alglib.kdtreequeryresultsx(kdt, r)
TextBox1.Text = alglib.ap.format(r, 1)
