Swapping Letters Using Regular Expression

I want to take a character array, find the first vowel and move it to the end. Some examples

• 'Fred' --> 'Frde'
• 'Replace' --> 'Rplacee'
• 'Cannot' --> 'Cnnota'

Is there a regular expression that will accomplish this with a single call to regexp?

Thank you

"Is there a regular expression that will accomplish this with a single call to regexp?"

There is likely no simple regular expression that will reliably detect the first vowel of every word in the entire English corpus, due to some letters which indicate vowels in some words and consonants in others (particularly w, u, and y).

Like most categorizations, it gets very blurred once you start looking in detail...

What is the first vowel of 'Queen' ?

What about 'Year' ?

Cwm ?

Gym ?

Sydney ?

Ytterbium ?

But not Yesterday...

Agreed. But the problem statement was just an example that would help me understand the regular expression syntax.

>> text = {'Fred', 'Replace', 'Cannot'};
>> regexprep(text, '([^aeiou]*)([aeiou])(.*)', '$1$3$2')
ans =
  1×3 cell array
    {'Frde'}    {'Rplacee'}    {'Cnnota'}
