can someone explain the error in this input for loop

Q0 = [];
for i=1:2
        p = input(sprintf('Enter value for p(distance) [%d model]:',i));
        v = input(sprintf('Enter value for v(velocity) [%d model]',i));
        a = input(sprintf('Enter value for a(acceleration) [%d model]',i));
        j = input(sprintf('Enter value for j(jerk)[%d model]',i)); 
        Q0 = [Q0 ; p ; v ; a ; j ];
        fprintf(Q0);
end

Enter value for p(distance) [1 model]:1
Enter value for v(velocity) [1 model]2
Enter value for a(acceleration) [1 model]3
Enter value for j(jerk)[1 model]4
Undefined function or variable 'Q0'.

I dont understand why its prompting me undefined variable.

It looks ok on my screen, but double check your initialization in case you initialized QO instead of Q0

[Travis Heckler]

No, it is Q0 both the places I dont know whats up with MATLAB

[Travis Heckler]

Okay so I literally made no changes and it worked after a few desperate attempts to run it, I officially dont understand MATLAB

If you can see the issue again, revert with the error message and the code you have used. Also correct the usage of fprintf command in the above code. You need to specify the format of the output field. For example, if you are expecting integers use.

fprintf("%d",Q0);
