FIND	Find indices of the non-zero elements.
 	I = FIND(X) returns the indices of the vector X that are
 	non-zero. For example, I = FIND(A>100), returns the indices
 	of A where A is greater than 100. See RELOP.
 
 	[I,J] = FIND(X) returns the row and column indices of
 	the nonzero entries in the matrix X.  This is often used
 	with sparse matrices.
 
 	[I,J,V] = FIND(X) also returns a column vector of the
 	nonzero entries in X.  Note that find(X) and find(X~=0)
 	will produce the same I and J, but the latter will produce
 	a V with all 1's.
