Finding all index for a given row and incrementing of every 10 indices - implement something like this and put it into a foreloop.

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))'];

Hello David,

Thankyou for you response it helps alot.

If I may ask a question for the value 1 and 20, that is where I was getting confused do I have to always specfify those values? what if the value are changing? beauce all I care is the increments of 5 and whatever the value is I will do the difference

[David Hill]

idx=find(ismember(a,yourValue));
