#Day42-Adding Numbers in Pair from a Vector-Iteration with resultant Vector

Task:

Write a code for adding numbers in pair in a vector(A), user input is vector(A) whose entry is added in pair and also add zero at the end and start position of vector B.Do the process for 4 times with resultant vector and return the answer as a matrix.
a=[1,2,3,4]
0 3 5 7 0 0 0 0
0 3 8 12 7 0 0 0
0 3 11 20 19 7 0 0

0 3 14 31 39 26 7 0
Note: This code can be done using the in-built command. But for the challenge, I am trying to avoid those
Matlab code

function b=trail_add_loop(a)

for k=1:1:4

b(k,1)=0;

j=2;

for i=1:1:length(a)-1

b(k,j)=a(i+1)+a(i);

j=j+1;

end

b(k,end+1)=0;

a=b(k,:);

end
