I need to find the name score of the names in a text file.

name point: David –> 4 1 22 9 4 = 4+1+22+9+4 = 40

Thanks for your help.

hello

this code does the trick :

ascii_value = uint32(yourstring); % convert your char / string into corresponding ASCII value
% let's converts ASCII values into values ranging from 1 to 26 (use offsets)
% uppercase letters
ind = find(ascii_value<91);
UL = ascii_value(ind) - 64;
% lowercase letters
ind = find(ascii_value>96);
LL = ascii_value(ind) - 96;
value = sum(UL) + sum(LL); %

MATLAB: Help with picking out the first and last word in a string

I would use numel(ind) instead of size(ind, 2), since ind is a vector.

As for your question, the first word is the content of Str up to the first space ( ind(1)-1) and the last is the content of Str from the last space( ind(end)+1), so:

 firstword = Str(1:ind(1)-1);
 lastword = Str(ind(end)+1:end);

NEW ANSWER: treats a word as one that starts with a letter

function wordcount = getWords
str = 'jeff john 2lion lion2 this2that dog.';
strcell = regexpi(str, '\w*', 'match');
%Defining word as one that starts with a letter (this2that would still be a word)
wordloc = cellfun(@(x) ~isempty(regexpi(x(1), '[a-z]')), strcell);
wordcount = sum(wordloc); %number of words
nonwordcount = sum(~wordloc); %number of non-words

%Displaying words /  nonwords
fprintf('Is a word: %s\n', strcell{wordloc})
fprintf('Not a word: %s\n', strcell{~wordloc})

Outputs:

Is a word: jeff
Is a word: john
Is a word: lion2
Is a word: this2that
Is a word: dog
Not a word: 2lion

OLD ANSWER: One way to do this without loops:

function getWords
str = 'jeff john 2td tomorrow 3e4 a23 dog.';
strcell = regexp(str, '\s+', 'split');
wordloc = cellfun(@(x) isempty(regexp(x, '[^a-zA-Z\.]', 'once')), strcell); %gets location of string with only letter a-zA-Z
wordcount = sum(wordloc); %number of words, 4
nonwordcount = sum(~wordloc); %number of non-words
