Let us say I have a series of dates: '01-01-2022', '05-01-2022', '06-01-2022' and I have corresponding data on these dates how do i convert the dates to an array that looks like this: [0,4,5]
Generally something like this:

Use function days
DateStrings = {'01-01-2022','05-01-2022','06-01-2022'};
t = datetime(DateStrings,'InputFormat','dd-MM-yyyy');
ans = 1×3
0 4 5

Your example and explanation are inconsistent: your explanation shows difference between adjacent dates, your example vector shows differences to the first date. Here are both:
C = {'01-01-2022', '05-01-2022', '06-01-2022'};
T = datetime(C,'inputFormat','d-M-u');
V = days(T-T(1)) % what your example shows
V = 1×3
0 4 5
D = [0,caldays(caldiff(T))] % what you explained
D = 1×3
0 4 1

Read about datevec. This will give you respective days from the dates.

I am sorry this is not what i wanted. Look at the original post. I want a vector that says how many days between the dates like this:
[0, days from date 1 to date 2, days from date 2 to date 3...., days from date n-1 to date n]
