Hi, I've got a code that gives me different outputs and I want to compare the messages inside them and the ones that are not in one string(X) and are in the other(Y) write them into another output. Lets see:
K is the number of messages that has an string.
If K from X is not in Y = L
And I do not want to use ismember or srcmp because the proces would be very long.
I guess I have explained myself.
Thank youuu for the answer!!!

I made an example of two imputs if you want the original inputs I can give you but they are this way mixing some letters with numbers and comas, etc

Presuming that your examples with invalid syntax are actually supposed to be string arrays:
a = ["qwert34776";"dnfien/8863";"feihfidi234";"939405'cncieni";"300oppdf";"din2004ms"];
b = ["qpwn3feini";"300oppdf";"hfgt4568";"qwert34776";"dnfien/8863"];
c = setdiff(a,b)
c = 3×1 string array
"939405'cncieni" "din2004ms" "feihfidi234"
Most likely using SETDIFF will be faster than writing your own function (including time to write, time to test, time to debug, time to maintain, and runtime).
