I have a list of strings (containing hockey player names) and I want to find the index for a specific name.I never had such an easy problem before and it is driving my insane.
I tried this:
player and index are both "Connor McDavid"
player = Player(1);
index1 = string(200);
logic = strcmp(index1 ,player);
Here are screenshots too ensure that they contain the same value.

logic should return a 1 but it returns 0. I tried == too but it doesnt help.
Pls help me, i dont know what to do anymore.

Haha, oh yeah, they are strings.
char(player)-'A'

160 is U+00A0, "non-breaking space"
player = replace(player, char(160), ' ');
index1 = replace(index1, char(160), ' ');
but it would probably make more sense to replace all of the 160 in your data source (perhaps immediately after retrieving it) instead of doing the replacement each iteration.

This can be solved by using the "ismember" function, refer the below example:
A = ["John"; "Lee" ; "James"; "Lee"];
B = "Lee";
index = ismember(A,B)
The output is
index =
4×1 logical array
0
1
0
1
