MATLAB: How to reset the sequence number for the sequence number in vector

Question

Reset the sequence number

I have 1 vector:

vec=[1, 2, 3, 4, 2, 1, 3, 8, 7, 9]

(lost 2 consecutive numbers 5, 6)

I want to reassign the above vector so that the sequence number is continuous.

That is, the above vector must be reset:

vec2=[1, 2, 3, 4, 2, 1, 3, 6, 5, 7]

How to do it, please help.

Answer 1

In your case:

[~,~,vec2] = unique(vec);
