Nested For Loop with Different Iterations

Hi,

Let's say I have a few different arrays:

ClearedIds = [0 3]

IDs= [0 0 0 1 2 2 3 3 3]

Num= [12 13 14 20 31 32 13 14 15]

StartNum=[12 13]

EndNum = [14 15]

Arrays ClearedIds, StartNum, and EndNum will always be the same dimension (1xn).

Arrays IDs and Num will always be the same dimension (1xn).

The program should essentially be able to do this: Check the values of array ClearedIDs. Wherever the values of array ClearedIds match elements in Ids, check where values of arrays Num match the elements in StartNum and EndNum. Store those indices.

The final result should be: IndNum = [1 3; 7 9]

I was thinking that for loops might help with this but so far have not had luck with the logical statements.

Please let me know if further clarification is required.

Thank you for your help.

What have you tried so far an which problems are you struggeling with?

Yeah, I don't see how the result given actually comes from the description as written...
