Loading data in the background?
6 views (last 30 days)
I have a set of code that does the following:
- Load a set of data
- Display the data
- Wait for the operator to make a judgement on the data.
- Record the user's judgement
- Repeat steps 1-4 for the next set of data (hundreds of datasets).
I have found that it takes about 5-10 seconds to load each dataset, and about 10-15 seconds for the user to make the judgement call. Unfortunately, the user is sitting idle while waiting for the data to load between sets.
Does anyone know how to load a .mat file in the background so that the next dataset can be loading while the user is in the process of making his/her judgement?
Thanks in advance.

TIMER objects seem to run in an own thread. Therefore you could load the data in a TIMER callback. But as usual for parallel programming, you have to be smart to avoid collisions between read and write access to the data.
