hi
I have this string:
str = ["a" "b" "c"]
which gives:
"a" "b" "c"
how can I have this new string with the previouse one:
new_str = "a" "c"
in other words, I want to delete "b" completely.
I have tried erase but with that I will have:
"a" "" "c"
thanks in advance.

Ran in:
How do you intend to identify the thing you want to delete? Do you simply want to delete the second string in the array?
str = ["a" "b" "c"];
str(2) = []
str = 1×2 string array
"a" "c"
Or do you want to delete all (or the first) instance of the string "b" in the array?
str = ["a" "b" "c"];
idx = strcmp(str,"b");
str(idx) = []
str = 1×2 string array
"a" "c"

Ran in:
str = ["a" "b" "c"];
y= find(contains(str,"b"))
y = 2
str(y) = []
str = 1×2 string array
"a" "c"
