zeros function: is this old syntax and what does this line mean? Error using zeros Size inputs must be scalar.

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);

This code was actually from 1993 and it worked back then. Maybe the syntax of zeros has changed in 25 years?
