word input codes in matlab

how to write a function that receives a word as input and returns a pig Latin translation of the word. Both the input word and the pig Latin word are character arrays. The pig Latin translation involves first determining if the input word begins with a vowel (a, e, i, o, or u). If so, append 'way' to form the pig Latin translation. If the input word does not begin with a vowel, then form the pig Latin translation by moving the first letter to the end of the word and then appending 'ay'. I also want to include a help option, so when the user types in "help" they get my pre written message

Hi Charlotte, is this a homework question? Did you try some code and struck somewhere?

[Charlotte Reed]

I'm trying right now, it's a practice question my prof provided

[Sriram Tadavarty]

Sure. That's good. Show till what you tried and that can be helped when struck. For some insights to get started look at this page https://www.mathworks.com/help/matlab/functions.html

[Charlotte Reed]

I found that site and got the help sentence coded, but I'm confused on how to actually make the commands for the vowels vs nonvowels and how they'll code

@Charlotte Reed: you could do this using indexing, ismember, and if. Give it a try!

Hi Charlotte,

Here is how you can perform this. Since you need to check if the first letter of the input word is vowel or not, you can use strcmp and strcmpi functions.

As you written the text already, i am just showing the way you can code it as below:

function out = pigLatinTranslation(word)
    
    % Check if the first letter of the word is vowel or not
    if any(strcmpi(word(1),{'a','e','i','o','u'}))
        out = [word 'way']; % Append 'way' to the word
    else
        out = [word(2:end) word(1) 'ay']; % Place the starting letter at the end and append the 'ay'
    end

end

This when tried as:

>> pigLatinTranslation('pple')

ans =

    'plepay'
>> pigLatinTranslation('apple')

ans =

    'appleway'

Hope this helps.

Regards,

Sriram

Simpler with ismember:

if ismember(word(1),'aeiouAEIOU')

[Charlotte Reed]

Thank you so much Sriram! It says there are not enough input arguements when I try to run it though?

[Sriram Tadavarty]

Run it by passing a word to the function as provided in the answer.

[Charlotte Reed]

I would like to have a line for the user to input a word, and then the code reacts for the piglatin answer. I'm not too sure what you mean by this?

[Sriram Tadavarty]

Sure.. Then update the above as such:

function out = pigLatinTranslation
   word = input('Enter a word:','s');
   ... % Then continue with the other commands in the answers
       % In the if condition, you could even use what Stephen as suggested
end

Hope this helps.

[Sriram Tadavarty]

Now use it directly with function name word2piglatin without any inputs

[Charlotte Reed]

Sorry, what do you mean by that?

[Sriram Tadavarty]

In the command window, directly run

>> word2piglatin
% This will prompt you to enter a word, then provide any character vector and then press enter
% you will get the output

[Charlotte Reed]

Got it!!! Thank you so so so much! :)

How would the code have to change for a phrase and wanting to translate it into pig latin?
