How to remove first consonant/consonant cluster and add it to the end?

I am honeslty so lost at what to do? I thought it was simple since I understand loops and such but I keep gettign stuck. I did some research and it seems like ismember is the way to go here but I alos understand how regexpri might also be used. But as I am a beginner, I am not sure if it the best to utlize that function.

Anyways this is what I want as my result:

desk --> eskd; hello --> ello; cup --> upc; switch --> itchsw; etc...

I appreicate any sort of help !

a = ["desk", "hello", "cup", "switch", "smith", "flowers", "angry", "decorations"]
for i = 1:length(A)
   if ismember xxxdd

       xxx
   end

Here is a little function, that can do this

a = ["desk", "hello", "cup", "switch", "smith", "flowers", "angry", "decorations"]
iWant = FirstToLast(a)

function out = FirstToLast(a)
out = squeeze(char(a))';
out(:,size(out,2)+1) = out(:,1);
out(:,1) = [];
out = strrep(string(out)," ","")';
end

Thanks! I am not familar with creating my own functions yet so I will be sure to return to your answer once I learn about it.

Again thanks so much :)

My pleasure. Matlab has a great documentation with many examples, which makes it easy to learn.

@Karen Landeros: Note that this answer does not do what your question requests.

The given code just moves the first character to the end. It does NOT identify any consonants at all (leading, single, clustered, or otherwise), nor does it move them to the end, as the questions requests (and your examples show).

To identify consonants the code would have to use:

• a regular expression, or
• isstrprop, or
• character codes, etc.

>> a = {'desk', 'hello', 'cup', 'switch', 'smith', 'flowers', 'angry', 'decorations'};
>> regexprep(a,'(^[^aeiou]+)(.+)','$2$1','once') % only leading consonant/s
ans = 
    'eskd'    'elloh'    'upc'    'itchsw'    'ithsm'    'owersfl'    'angry'    'ecorationsd'
>> regexprep(a,'([^aeiou]+)(.+)','$2$1','once') % first consonant/s (as question requests)
ans = 
    'eskd'    'elloh'    'upc'    'itchsw'    'ithsm'    'owersfl'    'ayngr'    'ecorationsd'

Note the difference for 'angry'
