finding parent words using strfind

As in normal case, i will have this huge cell array of words,

wordbank={'back'; 'beast';''fairytale';'aerial';'whale';'astronomy'.......}

I asked the user for a string of letters that might compare with what I have in the wordbank, so I tried to use strfind.

say,

wchoice=input('please enter a valid parent word','s')

then from here I tried to compare which word have similarities from the input with the list of words in wordbank.

so I used strfind(wordbank,wchoice)

which later will give me the cell with indices where the words are similar instead of just displaying what the word is.

I was hoping that something like this can appear if

wchoice='al'

I typed strfind(wordbank,wchoice)

ans=

'whale'

'fairytale'

Could you help me with this?Thank you.

wordbank(strfind(wordbank,wchoice))

I thought that would work before but matlab gave me this error instead:

??? Error using ==> subsindex

Function 'subsindex' is not defined for values of class 'cell'

Dear Walter,

is there another way of doing it though?I tried strcmp,and everything that I could with the level I know, but none of it worked out for me.

[Walter Roberson]

wordbank(~cellfun('isempty',strfind(wordbank,wchoice)))
