Clear[f]
Array[f, {3, 5}, {0, 0}]

{{f[0, 0], f[0, 1], f[0, 2], f[0, 3], f[0, 4]}, {f[1, 0], f[1, 1], f[1, 2],
    f[1, 3], f[1, 4]}, {f[2, 0], f[2, 1], f[2, 2], f[2, 3], f[2, 4]}}

{3,5} gives the dimensions of the array - the number of rows and columns.
{0,0} gives the starting values for the indexing.

hi,
i want to construct a list of the form:
{ f[1,1], ... f[n,m] }
So the list contains elements of the form f[i,j] with i ranging from 0
to n, and j from 0 to somebound[i].

What would be the most elegant way to this?
thanks
