vectorized non-linear matrix assignment

Let A be an m x n matrix (both m,n > 1).

let "X" p-by-1 be a set of row indices of A, and "Y" p-by-1 be a set of column indices of "A".

Suppose I want to assign the values of vector "V" p-by-1 to coordinates "(X,Y)" of "A".

Is there a way to vectorize this assignment?

e.g.

A = zeros(10,10);
X = [1 4 5  9];
Y = [ 2 2 1 8];
V = [1.1   2.98   -3  14];

i.e.

 I want to assign A(1,2) = 1.1  and  A(4,2) = 2.98  and A(5,1) = -3 and A(9,8) = 14.

something like "A(X,Y) = V", but that doesnt work.

Using the sub2ind function is the easiest way:

LI = sub2ind(size(A), X', Y');
A(LI) = V

+1. While this is of course the correct answer, it has always bothered me that there is not a more direct solution. Use of sub2ind is just too un-obvious to the new user.
