Subscripting Matrices (Syntax Question ?)


Hello,

I am constructing a matrix (whose dimensions I do not know in advance),
and later
on I want to index various elements in the array.

An index is in a form of a list, and want to use with a matrix but for
example
  mtx[[{1,3,2}]] = 0
will not set element  mtx[1,3,2].

Please help,
Thanks
