Pre invalidating space attitudes toward dating violence scales
Also, the set of vectors are independent because splitting $\bf x$ will always produce non-zero vectors, hence $a_1 a_2 ... I suggest you start here if you are interested in how this is done in a computationally efficient and of course provably correct way.
Perhaps the VDI error is just a symptom of a repairable disk corruption. An invalid pre-header implies corruption of the file, or means its not a VDI at all.
We know: 1) The null space of $A$ consists of all vectors of the form $\bf x $ above. 3) We need three independent vectors for our basis for the null space. 2) If you split up the general solution to $A=$ as done above, then these vectors will be independent (and span of course since you'll have $r$ of them).
So what we can do is take $\bf x$ and split it up as follows: $$\eqalign $$ Each of the column vectors above are in the null space of $A$. : Thank you for explaining the procedure of finding the basis of the null space.
That the null space has dimension 3 (and thus the solution set to $A=$ has three free variables) could have also been obtained by knowing that the dimension of the column space is 2 from the rank-nullity theorem. We may assign any value to their corresponding variable.
So, we set $x_2=a$, $x_4=b$, and $x_5=c$, where $a$, $b$, and $c$ are arbitrary.

I'm surprised that a power cut could corrupt a static part of the file...
