Error using zeros
Size inputs must be scalar.
From the line:
X=zeros(N,1:(n+1));
The code example is from year 1998, is this still valid syntax or is there something I don't just get?
Thanks for help.

The only time that code was valid was if n happened to be 0, in which case the code would have been the same as X=zeros(N,1:1) which would have been X=zeros(N,1) which is valid.
If you are trying to declare an array which is N by (n+1) then you need
X=zeros(N,n+1);
