Try this:
str_elem = Replicate(1, 3, 3, 3)
Cheers,

I think that will create a 3D matrix with all 'ones'. The structuring
element i need will look like this.
Str_Elem1 = [[0,0,0],[0,1,0],[0,0,0]]
Str_Elem2 = [[0,1,0],[1,1,1],[0,1,0]]
Str_Elem3 = [[0,0,0],[0,1,0],[0,0,0]]
Replicate cannot create this. Please tell me if there's any way to
create a 3D matrix like that.
Thanks,
Pushya.
