Find dates within date vector using master dates as reference

Hi,

please have a look into the attached files. I like to use the date vector in column 1 as master date:

This should be the expected output:

[26.11.1990,49.65,8.810,NaN,NaN,NaN,NaN,NaN]

.

.

.

[01.06.2020,171.65,-0.402,-0.4327,-0.103,-0.325,477,164]

How to organize that?

Certainly I can get the desired result using a for loop, but I am convinced that this can be solved smarter!

Best,

PR
