How to Pause a for Loop in Matlab to Create Snapshots?

So I'm sunning a code which solves an equation over a given period of time. As one would expect, the solution will change as time evolves so I wanted to create some sort of for loop which has the effect of creating "snapshots", which is to say I intend to pause the output at set intervals.

How might I go about implementing such a function?

I was hoping to implement something which pauses the code at defined intervals and then resumes execution on a button press.
