How to have the length of the words in each line

Hello, I am trying to write a function that gives me a matrix which shows the number of characters for each word of a textfile. for example if my text file is lyric = 'the cat is running on the wall', the answer shuld = [3 2 7 2 3 4] In order to do so, the function should a text file as an input and by using textscan in a for-loop format, it goes through the text and stops whenever it reaches the space and then it gives the number of characters from the first word to the last word. I appreciate if you can help me do this. Thank You,

Editing your question away angers the people who spend time helping and ensure they won't answer your question anymore.

I will ask mathworks to restore the question to its original state.

For information, the original question was how to use textscan to count the number of words in a text file.

I wouldn't use textscan for that. Probably the easiest would be:

 [wordstarts, wordends] = regexp(yourtext, '\w+');
  wordlengths = wordends - wordstarts + 1;

The advantage of the above is that it is unicode compatible. Anything that's not consider a letter by the unicode standard is a separator for your word count.

Use fileread to read the whole file in one go.

[wordstarts, wordends] = regexp(fileread(somefile), '\w+');
wordlengths = wordends - wordstarts + 1;
