I am writing a code where I have an array of a mix of positive and negative numbers. If the value of a number is negative I want to add 18 to that number.
for example A = [1 3 5 7 9 -2 -4 -1 6 5 4 3 ]
then magic
then A = [1 3 5 7 9 16 14 17 6 5 4 3]
thank you!

Hi Jacob,
As per my understanding, you want to add '18' to a negative number in the mix of positive and negative numbers.
Here is how you can do it:
A = [1 3 5 7 9 -2 -4 -1 6 5 4 3]
A(A<0)=A(A<0)+18 % add 18 to negative numbers
disp(A); % display the updated array
I hope this resolves your issue.
