I'm currently coding a function in MATLAB that has two steps:

1. It processes some data
2. It does some calculations on the processed data

I'm using the function to run a series of experiments, where I tweak the way calculations occur in step 2).

Seeing how I'm working with a large dataset and the data processing step takes a while each time, however, I'm wondering whether there is anyway to code in a "warm start" in the function.

That is to say, is there anyway to save all the progress that I've done after step 1) so that if I run the function a second or third time, it can skip step 1) and go right to step 2)?
