I want to remove a substring from an nx1 string, if I use the erase function, A = erase(Str, 'dog'). it works, however this is case sensitive and I would also like to remove all other case variations of 'dog' such as 'DOG', 'Dog', 'dOg' etc. if I use the functions upper(dog) it completely ignores the string 'Dog' and only removes 'DOG'. .
Is there a way to use the fuction while avoiding case sensitivity?

A = regexprep(Str, 'dog', '', 'ignorecase');
