menu and vector equal

In matlab I want to make a menu with this string array

material=["Rubber","Wood (along grain)" ,"Aluminum," "Titanium","Graphene","Steel","Cobalt-Chrome"]

if I exit out of menu I want to keep asking until a selection is made and when I select an object on the menu I want to output from the following vector

elasticity=[100000000,,11000000000.0000,69000000000.0000,110300000000.000,1050000000000.00, 200000000000.000 ,240000000000.000]

there are seven materials and seven numbers so if I select Rubber I want to output 100000000 and if I select Aluminum I want to get 110300000000.000

each material matches the number on the following vector

here is my code so

far

material=["Rubber","Wood (along grain)" ,"Aluminum," "Titanium","Graphene","Steel","Cobalt-Chrome"]
elasticity=[100000000,,11000000000.0000,69000000000.0000,110300000000.000,1050000000000.00, 200000000000.000 ,240000000000.000]
menu('Material',Mayerial(:,1)

matt - you don't mention what is wrong with your code or if you have tried to fix the obvious bugs with it. Do you really mean to use square brackets for the array of strings material? Do you really mean to have an empty value between the first and second element of the elasticity array? What is Mayerial in your call to menu (which is missing a closing bracket)? If you modify your code slightly to

material = {'Rubber','Wood (along grain)' ,'Aluminum', 'Titanium','Graphene','Steel','Cobalt-Chrome'};
elasticity = [100000000,11000000000.0000,69000000000.0000,110300000000.000,1050000000000.00, 200000000000.000 ,240000000000.000];
index = menu('Material',material);
if (index > 0)
    fprintf('material %s has elasticity %d\n', material{index}, elasticity(index));
end

then you might get what you are looking for. If the index is zero, then you can continue (using a while loop perhaps) to query the user for a material.
