I have a array of 19x2 double. >> matrix
matrix =
30.0000 20.0000
28.7500 17.5000
28.0000 16.0000
27.5000 15.0000
31.0000 22.0000
32.5000 17.5000
If I want to extract some numeric value of this double array (for example) according to the number of the ind variable
ind = find(A >= 0.123)
Where A is another variable related to matrix variable. How can I do?

Maybe you want
matrix(ind,:)

matrix(ind)
Since ind contains two indices in this case, you can do:
matrix(ind(1))
to find the value corresponding to the first index only.
