I have a set of unit vectors, but don't know their coordinates, or even the dimension of the space they span. I'm given the angle between each pair of vectors in units of some unknown "unit angle". I'd like to find the smallest dimension into which the set fits, as well as the range of values the "unit angle" is restricted to. Do I need anything more than linear algebra to solve this? -- Mike Stay Cryptographer / Programmer AccessData Corp. mailto:[EMAIL PROTECTED]
