Create an array with a for loop that refers to n user defined itterations

Hello,

I am trying to create an array of length n that is completely dependent on user prompted inputs. Here is the code that I have so far:

N = input('Enter Number of Nodes: \n'); Nnodes = 1:1:N; Npipes = 1:1:N-1;
for Nnode = 1:N
    X = input('Enter x-position: \n');
    Y = input('Enter elevation: \n');
end

For each iteration, I want the X and Y values to be stored as separate arrays.

Thank you!

"I want the X and Y values to be stored as separate arrays" Don't do this. Read the answers to know why this is a bad idea. Put the values in vectors.

Just put the values into vectors, like this:

N = str2double(input('Enter number of nodes: ','s'));
X = NaN(1,N);
Y = NaN(1,N);
for k = 1:N
    X(k) = str2double(input('Enter x-position: ','s'));
    Y(k) = str2double(input('Enter elevation: ','s'));
end
