Using the find function

A= magic(4)
for z= 1:4
position(z) = find(A(:,z)>10,1)
end

I want to use the find function to find all the values greater than 10 . this will enable me use the command A(position) to get all the values greater than 10 in a matrix. Is this possible with matlab?

Answer 1

[Thomas]

A= magic(4)
[row,col]=find(A>10)

should give you all positions of values in a Which are > 10

To find the actual values in A which are > 10 use

 A(A>10)

ans =
         16.00
         11.00
         14.00
         15.00
         13.00
         12.00

Thank you Thomas. The reason I am looking for the position is because I want to use these positions to access other values in a matrix named Zone. Zone is defined by: Zone = [3 5 7 9; 4 7 8 2; 4 6 7 8; 5 1 3 2]

So how do I relate the positions from A to the values I want in Zone? basically what I want from Zone is [3,7,1,3,9,8]. Is this possible?

Zone(A>10)

should do the trick..
