java matlab how can I run a jar inside a matlab script?

Question

I created a jar that basically parses a bunch of pdf/text files and creates a .mat file. I also have a matlab script that loads that .mat file and compares the data against some other data. I want to ensure that the jar runs and updates the .mat file first. I want the first line of my matlab script to execute the jar and wait for it to complete. How do I do this?

Answer 1

我通过使用system（'java -jar jarname.jar'）运行它

Answer 2

Make sure the jar is in your Matlab class path. Presumably there is some static method you use in the jar, so from matlab your script can just call com.mydomain.packagename.MainClass.main() . Control doesn't return to Matlab until that call is finished, and, presumably, the .mat file is created. So your next matlab line would be load('myfile.mat') . If this isn't working, can you be more specific?

Answer 3

Your Java api call must be blocking. Do not return from your Java parsing task until it is finished.
