Currently I am trying to write a code in MatLab (still learning, beginner). Below you can see the code I have written so far. For each axle an row of 5 values in the array is reserved for the parameters for each axle. (so the parameters of one axle is stored on the same line). Now I am trying to store the values in the array for each axle on a separate row. Somehow no rows are added to the array and the array size is still (1,5) instead of (n_axle,5). (n_axle value is defined by the user). What am I doing wrong and how could I solve this problem? I know I am pretty close, but I just can't find out where I went wrong. Thanks.

n_axles = input('define amount of axles');

count=0; j=0;

while count ~= n_axles

    wheel_parameters = zeros(n_axles,5);       %create # vector for # axles
    for j = 1:n_axles
        parameters1 = input('define load (kg)');
        parameters2 = input('define pressure (kpa)');
        parameters3 = input('recommended pressure (kpa)');
        parameters4 = input('define width (m)');
        parameters5 = input('define diameter (m)');
        wheel_parameters = [parameters1, parameters2, askparameters3, parameters4, parameters5]
        j = j + 1;
    end 
    count= count + 1;
end

Hello Dear,

I have modified your code. Now it is working as per your requirement.

   n_axles = input('define amount of axles');
    wheel_parameters = zeros(n_axles,5);       %create # vector for # axles
    for j = 1:n_axles
        parameters1 = input('define load (kg)');
        parameters2 = input('define pressure (kpa)');
        parameters3 = input('recommended pressure (kpa)');
        parameters4 = input('define width (m)');
        parameters5 = input('define diameter (m)');
        wheel_parameters(j,:) = [parameters1, parameters2, parameters3, parameters4, parameters5]
    end
