title: How to create database in MATLAB
body: <p>Actually I built a GUI to show the result of my program. When I click on the buttons, they need to read the input from a folder, which I choose for them, but I want to have a database to store all the data and load them just one time when I click on the button, not for all the buttons.</p>
  
  <p>I can give an example to show what I want to do: For example I can put a button just for loading the program and reading the input. Then, when I press any button, they don't need to read the data from the folder any more.</p>
  
  <p>I'll appreciate that anyone can help me.</p>
