Parfor problem --- "Array construction from ByteBuffer Threw an exception"

109 views (last 30 days)
Hi! I run my code using the 'parfor' function BUT receive an error message:
  • Array construction from ByteBuffer Threw an exception.
I am wondering what does this message mean in simple language? Any simple example could be great!
Thanks for your help!

@Walter Roberson Thanks again for your note.
My aim is to use 'parfor' to help separate my table into sub-groups, without imposing any summary statistics. In other words, somewhere like improving the code in https://www.mathworks.com/matlabcentral/answers/535864-how-do-you-split-a-table-into-sub-tables-based-on-entries-in-a-specific-column.
Anyway, I have already improved my code for better efficiency while keeping a tradtional 'for' approach.

Hi, I run into this error when using parfor as well. I found there was a undefined variable in my parfor loop. To check it, you may change your parfor to for, run it, and see what it says.
