Adding new values to an array using a loop

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
I've removed some unnecessary lines.

Thank you very much for helping me out! I guess I was thinking to hard and made it too complicated ;)

wheel_parameters(j,:) = [parameters1, parameters2,...]
Also, remove the line
j=j+1
The loop variable j will be incremented automatically.
