Sum question in Matlab

i'm confusing of how to sum two different vector in matlab

Scuh as v1=[1 2]

v2= [3 4]

and i wanna got the output of 10 which mean sum those number together

function [Vectors] = sumVectors(v1, v2)

Vectors = v1+v2;

end

this is the code i have done so far

Hii buddy,

There is something you want to know in matlab..

if u sum two vectors, it eventually results in to vector of individual sum of the elements. In your case v1+v2 results into a vector of [4 6], and if u want to sum all the elements in a vector use sum function. for example sum(v1) gives you the scalar value of 3 sum(v2) gives you the scalar value of 7. So you want to modify your code as Vectors=sum(v1)+sum(v2).

Oh my goddddd, that's the things I'm confusing. oh my god, thx for helping me figure it out.

cheers.

v1 = [1 2] ;
v2 = [3 4] ;
% MEthod 1 
v = [v1 v2] ;
iwant = sum(v) ; 
% method 2 
v = v1+v2 ;
iwant = sum(v) ;

i have tried that, seems like it's going to be work

but I got the value output of 1 2 3 4 when i'm using mt driver code to test the code

function [Vectors] = sumVectors(v1,v2)

Vectors = [v1 v2];

iwant = sum(Vectors);

end

and here my driver code

v1 = [1 2];

v2 = [3 4];

sum = sumVectors(v1,v2);

disp(sum)
