If I have a row vector,what command allows me to find the indexes that exceed a certain value that I want as a threshold. For example:
A =
0.1222
0.1350
0.1759
0.1110
0.1015
0.2599
0.1465
I would like in output the indices of the value grater or equal than 0.123, for example.

Use
ind = find(A >= 0.123)

And If I want to extract some the numeric value of an 19x2 double array (for example) according to the number of the ind variable how can I do?
