How to find the indices of elements in an array?

I have a 103x103 array of values, in which i have to take the smallest values and get the respective (i,j) indices of those values. Can someone help me out with this problem.

A = rand(100) ; 
[val,idx] = min(A(:)) ;
[i,j] = ind2sub(size(A),idx) ; 
val

val = 2.7946e-05

A(i,j)

ans = 2.7946e-05

If i want a set of numbers. For example if I want a set of numbers below 50 and if I have 10 such numbers, then how to get those indices?

Read about logical indexing.
