Hi Guys,
I have two string arrays i want to compare. They both contain the same arguments, but in one of them some arguments are there twice or more times. My problem is, that i want to like give every argument an index number, so that in both string arrays the same argument has the same index.
For example: {a,b,c,d,e,f,g,h} and {a,a,b,c,d,d,d,e,e,f,g,h} are my strings. And i want to have two double arrays: (1,2,3,4,5,6,7,8) and (1,1,2,3,4,4,4,5,5,6,7,8).
Is it possible to make this work? Cause my string arrays, are about 25000 and 35000 rows long, and i need to put them in the "same" format, so i can procede with my script.
I would be grateful for every help i can get.
Greetings
Nils

Ran in:
If stored in a cell arrary:
c1 = {'a','b','c','d','e','f','g','h'};
c2 = {'a','a','b','c','d','d','d','e','e','f','g','h'};
[~,ind] = ismember(c2,c1)
ind = 1×12
1 1 2 3 4 4 4 5 5 6 7 8
If actually stored as strings
s1 = string(c1)
s1 = 1×8 string array
"a" "b" "c" "d" "e" "f" "g" "h"
s2 = string(c2)
s2 = 1×12 string array
"a" "a" "b" "c" "d" "d" "d" "e" "e" "f" "g" "h"
[~,ind] = ismember(c2,c1)
ind = 1×12
1 1 2 3 4 4 4 5 5 6 7 8
