Is there any way to use im2java2d in a parallel pool worker?

I'm testing some java hash functions that take BufferedImage as input. I'm using im2java2d and now I would like to parallelize. Instead I get

IMJAVA2D is not available on this platform.

Is there a way out of this?

Hi Samuli,

Are you trying to call Java functions from MATLAB? Please attach a sample script, if possible. Are you using MATLAB "parfor" to parallelize your code?

Hi Tushar,

I managed to fix my issues in two steps.

1. Put all my java dependencies on the static class path via in ~/.matlab/R2105b/javaclasspath.txt (complete path with jar file name and extension)

2. copy im2java2d.m to my working directory and remove the abort code from the beginning of the script. Works beautifully.

I am using parfor and managed to run my code using multiple workers.

Hope this is useful for someone.
