Give multiple choice for Popup menu by code.

Hi every one , i have multiple features and multiple values for each. for example i have : name , age , sex , eye color , ... etc as a features and i have for every one multiple objects: for age i have 25,26,43,65,15,34,87,...etc therefore i suppose to work on multiple popup menu for every features there is a popup menu and when i run the code the use select only one value. My question is : Is popup is my best choice for that problem? if yes, how can i set the values in every popup menu automatically from matrix or from file (i dont need to select it manually because there is handred of values)

Popup is fine.

In order to set a popup menu's setting according to a matrix or file, you need to take the external representation of the value (e.g., 'blue' for eyes) and find it in the list of possible values. Take the index of the desired value down the list, and set() the handle's 'Value' parameter to that index.

Sample:

eyecolors = {'Unknown', 'blue', 'green', 'grey', 'brown'};
h = uicontrol('Style','pop', 'String', eyecolors);

...
thiseyecolor = 'grey';

[tf, idx] = ismember(thiseyecolor, eyecolors);
if tf
  set(h, 'Value', idx)
else
  warning(sprintf('What? Eye color is "%s" ??', thiseyecolor));
  set(h, 'Value', 1);
end

this is good for one popup menu , but if i want to make mulyiple popup menu that appear in the Figure at the same times , may be i have 10 popup in one sample and in another sample may be 20 popup , so is there any idea about making multiple popup with diffrerent values for each one.

menuchoices = {{'Unknown', 'blue', 'green', 'grey', 'brown'},
               {'Unknown', 'male', 'female', 'other'},
               {'Unknown', '25', '26', '43', '65', '15', '34', '87'}};
nummenu = length(menuchoices);
menuhandles = zeros(nummenu, 1);
for K = 1 : nummenu
  menuhandles(K) = uicontrol('Style', 'pop', 'String', menuchoices{K}, 'Value', 1, 'Units', 'norm', 'Position', [0, (K-1)/nummenu, 1/10, 1/(nummenu+1)]);
end

Now you can iterate over the menuhandles, doing comparisons to menuchoices{K}
