how can I delete from a string a couple of lines I have indexed

Hi so I've got a string and I've got a variable that contains the position of different messages from the string. How could I delete the lines I got in the variable?

If it is a string array, and you want to remove a portion of a string in the array consider using eraseBetween:

newStr = eraseBetween(str,startPos,endPos)

If you have an array where each row contains a string, and you just want to remove entire rows, use indexing to set those rows equal to [].

myStr(rmvPositions) = [];

Are you looking for something like this?

str = ["line 1";"line 2";"line 3";"line 4";"line 5"]

str = 5×1 string array
    "line 1"
    "line 2"
    "line 3"
    "line 4"
    "line 5"

var = [2 3];
str(var)=[]

str = 3×1 string array
    "line 1"
    "line 4"
    "line 5"
