Given an input vector
nums = [1 2 3 1 3 3 1 2 2 3 2 1 3];
I'd like to loop through and create groups such that when an element is repeated, everything before it is a group (new vector). For example, using the vector above, the groups would be:
[1 2 3] [1 3] [3 1 2] [2 3] [2 1 3]
To elaborate, the first group stops at 3 because everthing is unique until that second 1 is reached because it's a repeat of index 1. Then the second group starts at that index for the second 1, reads through and sees that 3 repeats, so everything from that second 1 to the next 3 is a group. Then it starts at the next index...
Basically each group needs to have non-repeating values.
Thanks in advance
