dx_n0 = (dx);
Theta_n0 = poolData(x,n,polyorder,usesine);
m = size(Theta_n0,2);
total_n0(i,:) = [dx_n0 Theta_n0];
end
I currently have the above code but am receiving the error "Index in position 1 is invalid. Array indices must be positive integers or logical values.". Is it possible to run this code through the range of values and save each resulting dataframe separately?

I also don't have function poolData, but from your description in comment, the error seems to be related to dimensions of dx_n0 and Theta_n0.

It would be more helpful, if you could copy the entire error message you get while posting the question in the forum. I guess the issue might be with the value of 'i'. You can make use of breakpoints to debug the issue much easily.
If that's no the case other workaround would be to possibly define 'total_n0' to be a cell array, to store variable length arrays.
total_n0{i} = [dx_n0 Theta_n0];
Hope this helps!
