MATLAB: Addition of numbers in array

additionarray

Lets' say I have 2 vectors:

x = [7 4 6];
y = [1 4 4];

But these are not just vector consider them as A number, i.e., 746 and 144. Now I want to add these numbers (as we do on paper, carry method).

so the answer should be 890.

and want display like:

7 4 6
1 4 4 
-----
8 9 0

Please help me to code.

Thanks

This is one way

x = [7 4 6];
y = [1 4 4];
z = sscanf(sprintf('%d',x),'%d')+sscanf(sprintf('%d',y),'%d')

MATLAB: How to find length of user input

Hi,

a lots of bugs in this - i think i fixed them all:

clc
clear
isbn = input('Enter a nine digit ISBN number:' );
isbn = char(string(isbn));
if strlength(string(isbn)) == 9   
    d1 = str2double(isbn(1));
    d2 = str2double(isbn(2));
    d3 = str2double(isbn(3));
    d4 = str2double(isbn(4));
    d5 = str2double(isbn(5));
    d6 = str2double(isbn(6));
    d7 = str2double(isbn(7));
    d8 = str2double(isbn(8));
    d9 = str2double(isbn(9));
    A = (d1 * 1 + d2 * 2 + d3 * 3 + d4 * 4 + d5 * 5 + d6 * 6 + d7 * 7 + d8 * 8 + d9 * 9);
    d10 = mod (A, 11);
    
    if d10 ~= 10
        fprintf ("ISBN-10: %d-%d%d-%d%d%d%d%d%d-%d\n",d1, d2, d3, d4, d5, d6, d7, d8, d9, d10);
    elseif d10 == 10
        d10 = 'X';
        fprintf ("ISBN-10: %d-%d%d-%d%d%d%d%d%d-%s\n",d1, d2, d3, d4, d5, d6, d7, d8, d9, d10); 
    end
    
else
    if length(isbn) ~= 9
        disp ('Error, ISBN must be exactly 9 digits.')
    end
end

Best regards
