Pig Latin Converter Function
显示 更早的评论
Hello all,
I am trying to write a function which takes a string as input and converts it to Pig Latin string. For example, 'pig latin in matlab' would become 'igpay atinlay inay atlabmay'. So everything before the first vowel is shifted to the end of the word and following by 'ay'.
I know that I can use find to find the first vowel in each word. But then how do I move the characters to the end of each word and append 'ay' to it?
Here is what I have so far:
function [ new_string ] = pig_latin( string )
each_word = [];
temp = '';
ay = 'ay';
words = strsplit(string,' ');
num_words = numel(words);
for j=1:num_words
temp = words{j};
vowel = temp(find(ismember(temp,'aeiou'),1,'first'))
vowel_loc = find(vowel,1,'first');
end

clc; clear all ;
str = 'pig latin in matlab' ;
C = strsplit(str) ; % split the string
%%chnage accordinhly
s0 = 'ay' ; % which has to be joined
l = cellfun(@(c)[c(2:end) c(1)],C,'uni',false) ;
m = cellfun(@(c)[c s0],l,'uni',false) ;
iwant = strjoin(m)

You can read the respective documentation....
[x y] works like joining two strings, where x and y are two strings. cellfun applies a specified function to all the cells.

this isn't perfect though... if you start a word with a vowel like "other" it returns theroay

Is this solved yet? You accepted this answer but seem to indicate it's not right. What about my answer below? Is that right?

vowels = {'a' 'e' 'i' 'o' 'u'} ;
str = 'pig latin in matlab' ;
C = strsplit(str) ; % split the string
l = cellfun(@(c) c(1),C,'uni',false) ;
% get vowels pos
idx = ismember(l,vowels) ;
C1 = C(~idx) ;
%%chnage accordinhly
s0 = 'ay' ; % which has to be joined
l1 = cellfun(@(c)[c(2:end) c(1)],C1,'uni',false) ;
m1 = cellfun(@(c)[c s0],l1,'uni',false) ;
%%work on vowel
C2 = C(idx) ;
m2 = cellfun(@(c)[c s0],C2,'uni',false) ;
%%Replace strings back
m = cell(size(C)) ;%
m(~idx) = m1 ;
m(idx) = m2 ;
iwant = strjoin(m)

How about this:
To call:
new_string = pig_latin('pig latin in matlab other')
Function declaration
function [new_string] = pig_latin( string )
new_string = '';
ay = 'ay';
words = strsplit(string,' ');
numWords = length(words);
for k = 1 : numWords
thisWord = words{k};
firstVowel = thisWord(find(ismember(thisWord,'aeiou'),1,'first'));
vowelLocation = strfind(thisWord, firstVowel);
if vowelLocation >= 2
% Start the new word at the vowel location.
newWord{k} = [thisWord(vowelLocation:end), thisWord(1:vowelLocation-1), ay, ' '];
else
% If word starts with a vowel, just add 'ay'.
newWord{k} = [thisWord, ay, ' '];
end
end
% celldisp(newWord);
% String cells together to form the output character array.
new_string = [newWord{:}];
Shows in command window:
new_string =
igpay atinlay inay atlabmay otheray

You're welcome. I tried to keep it somewhat simple and straightforward, and on your level and similar to your existing code. Maybe you could at least "Vote" for my answer.
