Question

Using MATLAB code

Assume you have a single row vector stored in a variable. You do not know how many elements are in the vector. Write your own code that sums all the elements in the vector. You are not allowed to use "sum" or any form of loops. (Hint: Use vector characteristics. It will be a single line code.)

Answer 1

Code for adding the elements in the vector

**************************************************

>> A = [1 2 3 4 5 6 7 8 9]

A =

1 2 3 4 5 6 7 8 9

>> norm(A,1)

ans =

45

*****************************************************

Steps:

# Assign a vector of any length A

# To add the elements in the vector using the command norm(A,1)

norm(A,1) takes the absolute value for each element in the vector and adds it.
