I have the following data:

mass = [ 23 45 44]
velocity = [34 53 32]
time = [1 2 3]
acceleration = [32 22 12]
speed = [12 33 44]

What I'm trying to achieve is to apply uicontrol that creates two lists with this data (mass, velocity, time, acceleration, speed), and have the ability to click on one of the variables (mass) in each column and there is a numerical data output, like mass = 23 45 44

Output: numerical data stored in these variables

Here is the code:

function learnlists()
figure;
yourcell={'mass','velocity','time','acceleration','speed'}
hb = uicontrol('Style', 'listbox','Position',[100 100 200 200],...
'string',yourcell,'Callback',@measurements)
yourcell={'mass','velocity','time','acceleration','speed'}
hc = uicontrol('Style', 'listbox','Position',[300 100 200 200],...
'string',yourcell,'Callback',@measurements)
function [out] = measurements(hb,evnt)
outvalue = get(hb,'value');
v = get(hb,'value')
if v == 1
    mass = [1 2  3 4 5]
elseif v == 2
     velocity = [ 1 2 3 4 5]
end
end
     end

Thanks,

Amanda

Do you mean like this:

function learnlists
clc;
format compact;
format long;
figure;
yourcell={'mass','velocity','time','acceleration','speed'}
% Create first listbox.
uicontrol('Style', 'listbox','Position',[100 100 200 200],...
  'string',yourcell,'Callback',@measurements)
% Create second listbox.
uicontrol('Style', 'listbox','Position',[300 100 200 200],...
  'string',yourcell,'Callback',@measurements)
function [out] = measurements(handleToParentControl,evnt)
mass = [ 23 45 44];
velocity = [34 53 32];
time = [1 2 3];
acceleration = [32 22 12];
speed = [12 33 44];
selectedItem = get(handleToParentControl,'value');
% Print selected array to command window:
switch selectedItem
  case 1
    mass
  case 2
    velocity
  case 3
    time
  case 4
    acceleration
  case 5
    speed
end
