Increase Java Heap Space for a appliction created by Matlab Application Compiler

Dear all,

for a compiled application I get the following error message during reading big xml-files: java.lang.OutOfMemoryError

I already read how to increase the java heap space in Matlab in the settings. This helps by executing the code directly in Matlab but not for the executable.

Is there a way to increase the java heap space also for the executable (performed with Matlab Runtime 9.2)?

Thanks a lot!

You can add a java.opts file to the "Files installed for your end users" section, at the bottom of the deploy-tool window, next to where the exe filename is displayed. In the java.opts file you can place JVM startup parameters, including the -Xmx parameter, for example -Xmx512M or -Xmx2G
