Pause until input from one of two buttons

You can also unpause uiwait with uiresume, not just by closing the figure.

Hi, there is a (1x6) vector that i want to extract values from. I used strings to pick-up the subtitle and now the problem is that i have to extract every value under the subtitle (e.g Oxygen). How to i extract those values without hardcoding ?

It would probably make a more sense to use the table data type instead of a string array that is parsed to separate variables. ...
