I am using contourf to represent matrices visually. I have multiple matrices that I need to be able to access easily in my GUI window. My query was, is it possible to use the arrows of a UI slider to navigate through different contourf plots?

So, from what you know about the UI slider, if I set up a code to allow the user to select a folder to open files from, would it be better to open the files in the workspace and call them when navigating with the slider or open them individually when navigating through with the slider? Thanks

It depends entirely how large they are, how long they take to open, how many the user is likely to scroll through, etc.

It is an upfront cost in time and memory vs an on-demand cost. If you can store them all in memory and the upfront time is not a problem then certainly being able to scroll through things quickly is good.

But if you have 100 large files and the user is likely to only look at a couple then the time and memory taken loading them all in is clearly not warranted.
