finding parent words using strfind

1 次查看（过去 30 天）

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.
