how to ask users to input different number of values at each time according to a specific condition

There is a code that presented in the following, that I want to ask users to input different number of values according to a specific condition (i.e. rock_code). Since size(rock_code,1) equals different values each time (=1,2,3,4,5...), so the user needs to enter the value of the corresponding quantity

 a=zeros(1,size(rock_code,1));
for i=1:size(rock_code,1)
string=['Enter the vecter numbers of ' int2str(i) ':'];
a(i)=input(string);
end

So, is it possible to create a interface to ask user to input different quantity values at each time according to the specific condition (i.e. rock_code), like using inputdlg function? Could you please give me some solutions as I do not know how to do that?

strings = compose("a(%d)", 1:size(rock_code,1));
data_str = inputdlg(strings);
a = str2double(data_str);

Thanks for your help, but this code can only input one value

I tested the code. It does permit entering multiple values. For example

rock_code = randi(9,3,1);

and then run the code, then it will prompt for three values

Thanks for your help, it works!
