When I try to create y(subscript)series as shown in to create initial series with n = 11, I get the message "this variable is undefined." What am I doing wrong?

Thanks for your kind words. I am having trouble implementing WE's suggestion in creating the initial series. I am in touch with him(her?)

I am attaching another file where I have reproduced your suggestion up to creating an initial array when I run into a problem. Could you kindly let me know where I am going wrong?

The index in my S.old is not a vector/matrix index but a literal index. You get it by simply typing a period "." after "S" and then continue with "old" (all without the quotes).

Thank you for the clarification. I tried it it works up to a point. But it looks like I may still have a problem as I proceed. I will work on it to see if I can resolve it by myself. If I cannot I hope I can get back to you.

Hello Mr. Werner

I was able to navigate the remaining parts successfully. The responses by Mr. Diaz and yourself are greatly appreciated.

I still have a small problem. Increasing the value of n I find the array of the results become huge. Is there any way that only last two or three columns of the results can be displayed?
