Yes. That makes sense. Do let me (and others) know, what solution you came up with,

How did you calculate the eigenvectors?

comment Placing points in $\Bbb R^n$
When there is a set of $r$ points among those $n$ points, using which you can express all the $n$ points as a linear combination. Moreover, there is no other set smaller in size which can do the same.

$10000 \times 10000$ is easily manageable inside current matrix tools like matlab, R, octave, numpy etc. Why do you want an algorithm for that? Please give more context to your question. Are you implementing this in a time constraint system where this kind of resources are not available? Do you want to do this for lot of matrices of same dimension?. This will help others to answer your question in a better fashion.

Yes, I do know you harish. We were neighbors in hostel as well :):).

comment zeros of $x^*Ax$, a quadratic form
You are right. It is far from stating the answer. I thought the reverse transformation is obvious. I have now explicitly stated it.
