Hello all,
If I had a martix of 5 by 10, and in each of the index(s) there are numbers that increment.
example:
row(1), col(all) = 1, 3, 6, 19, 20, 21, 50, ... so on
row(2), col(all) = 2, 5, 6, 15, 16, 30, 54, ... so on
:
:
so on
Then the indexes (1) and (5) which the values are 1 and 20. How do I implement something like this and put it into a foreloop.
Now I looked into find command for Matlab, but can't make sense of how to properly implement it into my code for finding two of the indexes like I explained above.

idx=[find(ismember(a,1))',find(ismember(a,20))'];
