I have a problem in setting this right.

I have this struct,

wordstruct =

    a: {'amal'  'asyik'  'ampun'}
    b: {'bola'  'busuk'  'basi'}
    c: {'cacing'  'campur'  'cucuk'}
    .
    .
    .
    z: {''..........''}

i want to compare an input of a string with a word in one of the fields in the struct so i tried this,I want to display that if the word does not exist, it'll say the word is invalid.

I know that if I have this line of code and the word does exist, it'll show me something like this,

word='bola'

(strfind(wordstruct.(word(1)),word);

ans =

[1] [] []

and if word='bell' %does not exist in struct

ans =

[] [] []

however im having difficulty to represent the empty cell in my if statement where i have it like this:

if (strfind(wordstruct.(word(1)),word)= %%%%IDK this part

fprintf('this word is invalid');

else

fprintf('%s is in the wordbank',word);

end

Does this help?

wordstruct.a = {'amal'  'asyik'  'ampun'};
wordstruct.b = {'bola'  'busuk'  'basi'};
wordstruct.c = {'cacing'  'campur'  'cucuk'};
word = 'bola';
if any( strcmp( word, wordstruct.('b') ) )
   disp( 'found the word' ) 
else
  disp( 'failed' )  
end
