App designer for composite bars for n inputs

Hey there, I am trying to build an app for composite bars, the inputs depend on the user's requirement. How do i get multiple inputs window ? (for ex: if n= 10, the edit field boxes must be the n for further inputs (i.e 10). Here's my code for the same on matlab

disp('1 - Circular cross-section');

disp('2 - Rectangular cross-section');

choice = input('Enter the type of cross-section: ');

n = input('Enter the number of cross-sections: ');

F = input('Enter the load in N: ');

if choice==1;

A=zeros(n,1)

Delta=A;

for i=1:n

fprintf('Enter the Youngs modulus of Bar %i : \n',i );

E = input('y =');

fprintf('Enter the length of Bar %i: \n',i );

L = input('b =');

fprintf('Enter the diameter of Bar %i:\n',i );

D = input('s =');

A(i,1) = (pi*(D^2)/4 );

Delta(i,1) = ((F*L)/(A(i,1)*E ));

end

for j=1:n

fprintf(' Total extension of the bar %i: %f. \n' ,j,Delta(j,1 ) );

end

elseif choice==2;

A=zeros(n,1)

Delta=A;

for i=1:n

fprintf('Enter the Youngs modulus of Bar %i : \n',i );

E = input('y =');

fprintf('Enter the length of Bar %i: \n',i );

L = input('b =');

fprintf('Enter the breadth of Bar %i:\n',i );

D = input('s =');

A(i,1) = L*D;

Delta(i,1) = ((F*L)/(A(i,1)*E ));

end

for j=1:n

fprintf(' Total extension of the bar %i: %f. \n' ,j,Delta(j,1 ) );

end

end
