delete an element from string

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.

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"

Thank you DGM for both.

or

str = ["a" "b" "c"];
str(str=="b") = []

str = 1×2 string array
    "a"    "c"

str = ["a" "b" "c"];
y= find(contains(str,"b"))

y = 2

str(y) = []

str = 1×2 string array
    "a"    "c"
