I have the following string, now I want to splits it up in 2 different strings like show in below:
STR = ["van Donk","Gerritsen","kooijman","Verliefde","Floré","Pengel","aan de Wiel","van der Hoeven","Hop","Boer","van Ewijk"]
What i want to create is
STR1 = ["van","","","","","","aan de","van der","","","van"]
STR2 = ["Donk","Gerritsen","kooijman","Verliefde","Floré","Pengel","Wiel","Hoeven","Hop","Boer","Ewijk"]
Anyone who can help me?

Ummm... why? "van der Hoeven" is a complete surname. The surname is not "Hoeven" with "van der" being some kind of middle name. "van der Hoeven" should be sorted under v or V, not under H

"The surname is not "Hoeven" with "van der" being some kind of middle name."
The "van der" is not part of the main name, it is a tussenvoegsel:
https://en.wikipedia.org/wiki/Tussenvoegsel
which in Dutch is ignored when sorting, just like "von" and "zu" are ignored in German.
""van der Hoeven" should be sorted under v or V, not under H"
There are differing opinions on this:

So the required sort order depends mostly on where your users are from.

Ran in:
str = ["van Donk","Gerritsen","kooijman","Verliefde","Floré","Pengel","aan de Wiel","van der Hoeven","Hop","Boer","van Ewijk"]
str = 1×11 string array
"van Donk" "Gerritsen" "kooijman" "Verliefde" "Floré" "Pengel" "aan de Wiel" "van der Hoeven" "Hop" "Boer" "van Ewijk"
tkn = regexp(str,'^(\w+\s+)*(\w+)$','tokens','once');
tkn = vertcat(tkn{:});
st1 = strtrim(tkn(:,1))
st1 = 11×1 string array
"van" "" "" "" "" "" "aan de" "van der" "" "" "van"
st2 = tkn(:,2)
st2 = 11×1 string array
"Donk" "Gerritsen" "kooijman" "Verliefde" "Floré" "Pengel" "Wiel" "Hoeven" "Hop" "Boer" "Ewijk"

(.*)\s+(\S+)
What do you want to do if there are spaces after the last word?
