Here is a solution in just one line using one regexprep call:

>> str = 'the quick brown fox';
>> out = regexprep(str,{'(?![aeiou])[a-z]','[aeiou]'},{'c','v'},'ignorecase')
out =
ccv cvvcc ccvcc cvc

Note that it correctly identifies only consonants and vowels: non-alphabetical characters are simply returned unchanged:

>> str = '123: Hello, World!';
>> out = regexprep(str,{'(?![aeiou])[a-z]','[aeiou]'},{'c','v'},'ignorecase')
out =
123: cvccv, cvccc!
