regexprep is vectorized. Also, if you want to match only the whole word
"dog" and not match "dog" in, say, "dogged pursuit", then use \< and \>:
>> a = {'my dog has fleas','dogged pursuit','horse, dog, pig'};
>> b = regexprep(a,'\<dog\>','cat')
b =
'my cat has fleas' 'dogged pursuit' 'horse, cat, pig'
If you really just want to replace ALL instances of "dog" with "cat" then
>> b = strrep(a,'dog','cat')
b =
'my cat has fleas' 'catged pursuit' 'horse, cat, pig'
