Dear All,
Could you please help me solve the problem seen below?
Create a Matlab script file, which asks the user for a 'n' number and the program displays the 'n'th Schröder number (for example n=9, 9th number).
Thank you in advance!!

I show you how you could solve your problem.
Try this code:
prompt = 'n: ';
n = input(prompt); % ask the user for a 'n' number
S = zeros(1,n); % init Schroder number vector
S(1) = 1; % init S0
for ii = 2:n
TempSum = 0;
for kk = 1:ii-1
TempSum = TempSum + S(kk)*S(ii-kk); % compute sum
end
S(ii) = S(ii-1) + TempSum; % compute S(n)
end
disp(num2str(S(n))) % disp to command window S(n)
In future it is important that you try to start with some code and then we can help you on how to continue/fix your code to obtain the solution.
Hope this helps.
