I need to sum value in matrix but I can't use "sum". So, Can I sum value in matrix with if-else or while loop? How to create it. Assume I have matrix C=[ 1 2 3 4 5 6 7 8 9 ]
Thank You

Because you "can't use sum", I assume this homework. Show what you've tried so far, and maybe we can give you some hints.

Yes. You can use a while loop, or a for loop. I don't see how an if could be used. See this, and if you have trouble creating the code read this If it's homework, please add the tag "homework" and if it's not homework, say so explicitly.
