I am new to Matlab. How would I write a program to merge two arrays at a time multiple times. I have 13 arrays that need to be merged with each other once. Thank you.

Merge in what sense? Sum? Concatenate? In which direction?

You can use the square brackets to concatenate arrays, or you can use the cat function.
[A;B;C]
cat(3,A,B,C)

Hello Grace,
You can simply concate 2 or more arrays in below fasion.
If A and B are 2 row arrays and you want A being appended by B, then...
Appended_A_by_B = [A B];
Will give you this result.
If A and B are column arrays then....
Appended_A_by_B = [A; B];
There is also a function cat which can be used to concatenate arrays or matrices. You can know more about it here:
Cheers
