Hi, I'd like to create a matlab gui, in which through a button,I can change the value of a variable defined in the workspace. The problem is that i don't know how to pass the variable to the callback function, linked with the button.Thank you

In the callback function for the button, use the assignin function to modify the value in the base workspace.
For ex.
modified_value = 100;
assignin('base','var', modified_value);
where ' var' is the variable to be modified (assuming you know which variable in the base workspace has to be modified)
