You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: icatb_verSliderCallback.m
    path of file: ./repos/gift/GroupICAT/icatb/icatb_display_functions
    
    the code of the file until where you have to start completion: function icatb_verSliderCallback(handleObj, handles)
% vertical slider callback - Sets some of the controls invisible when
% scrolled up or down.
% 
% Input:
% 1. handleObj - Handle for object. Set user data for the object as a structure with the
% following fields 'maxHeight', 'minHeight', 'initialYPositions', 'tag'.
% 2. handles - Handle for the figure
%
% Output: none


% Get the user data
sliderData = get(handleObj, 'userdata');

% get the data information
initialYPos = sliderData.initialYPositions;
maxHeight = sliderData.maxHeight;
minHeight = sliderData.minHeight;

% Tags for the controls
tagFig = sliderData.tag;
