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); %

here is it
sentence = 'His story is told in the first book of Samuel and his life as a king in the second book of Samuel and at the beginning of the First book of Kings';
STR = split(sentence);
for ci = 1:numel(STR)
value(ci) = subfct(char(STR(ci)));
end
function value = subfct(yourstring)
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); %
end

Name = 'David';
Num = lower(Name) - 'a' + 1; % 'a' -> 1, 'b' -> 2, ...
Score = sum(Num);
[EDITED] You mention in comments, that you want to do this for "names in a text file". Do the files contain one name per line?
Str = fileread('YourTextFile.txt');
Str(Str == char(13)) = [];
CStr = strsplit(Str, char(10));
Score = zeros(size(CStr));
for k = 1:numel(CStr)
Score(k) = sum(lower(CStr{k}) - 'a' + 1);
end

@Mathieu NOE: I'm very happy that we are fighting together to get the best solution for the question. Seeing different approachs is useful to understand the power of MATLAB.

@Jan : tx for your nice comments , but I'm not yet to your level - still I like to see how tricky problems can be solved elegantly by knowledgable people like you and others contributors here.

im late to the show, but here we go anyway...
clear
clc
name = 'david';
a = {'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'};
total = 0;
for i=1:length(name)
arr = cellfun(@(x)isequal(x,name(i)),a);
[row,col] = find(arr);
total = total + col
end
