I want to define a function VectorToMatrix[list_, n_] that behaves as
follows:

VectorToMatrix[{a,b,c,d,e,f,g,h,i,j}, 4]//MatrixForm

0 a b c d
0 0 e f g
0 0 0 h i
0 0 0 0 j

Now n can be determined from Length[list], which will always be equal to
n choose 2 for some n. But I would rather input n to save that
computation. (I will be doing this for a lot of vectors.)

Any ideas?
