dear frind ,

instead of trying to write the sigma (i cant remember that it exisits) do a for loop on the addition between two variables (the new one , and the summation of all the previous)

if that helped you please press on the Helped me button

The 2 sums are just convolution of 2 signals.

You can use the matlab conv function. Read help for this.

If you need to implement the convolution yourself tell me and I will provide you a .m file with it!

If it helped you: click helped me, please!

use the cumsum command, and remember think in terms of vectors.

Thanks for your help, but I solved the problem I used matrix - vector form and
then easily made the convolution instead of dealing with loops
