How can I format with fprintf to show 2 seperate listsas the output?

Introductory course into matlab assignment. Im trying to list the n and A outputs into column list but can get the format right. They mix in between each other.

function [A] = Loanpayment( p,i);
n = input('Number of payments: ');
%A calcualtes the annual payment to be made
%P= Initial loan amount
%n= Annual payments agreed upon, in this case 5 payments were agreed 
%i= Interest rate on P, loan amount
A = (p).* ((i.*(1+i).^n)./((1+i).^n -1));
z = linspace(A,0,n);
y = [1:n];
fprintf('Number of Payments          Payment amount\n')%List of Number of...
%payments and amount per payment
fprintf('%g %25.3f \n',z)
fprintf('%g %25.3f \n',y)
end

You have to transpose the z and y in fprintf.

Try this

function [A] = Loanpayment( p,i)
n = input('Number of payments: ');
%A calcualtes the annual payment to be made
%P= Initial loan amount
%n= Annual payments agreed upon, in this case 5 payments were agreed 
%i= Interest rate on P, loan amount
A = (p).* ((i.*(1+i).^n)./((1+i).^n -1));
z = linspace(A,0,n);
y = [1:n];
fprintf('Number of Payments          Payment amount\n')%List of Number of...
%payments and amount per payment
fprintf('%g\t%25.3f \n', [y; z])
end

Note for the above purpose that it is important in the fprintf() that y and z are row vectors rather than column vectors. The [y;z] then gives a 2 x something array with the first element in each column being y and the second element in the column being z. Then fprintf() always goes "down" columns -- the %g would be applied to the first entry in memory, the %25.3f would be applied to the second element in memory, and that is the end of the % formats so %g would be re-used for the third element in memory which is the second y, %25.3f would be re-used for the 4th element in memory, which would be the second z, and so on.

You should also have a look at compose() which has a more natural behaviour.

Thank you, this is what I wanted it to do. Much appreciated!
