Passing a data file to a function in parfor or parfeval

I want to pass a data file to process in parallel. Same data file to be used by each worker for complete process and each worker should process the whole datafile.

So what's your problem?

I want to do signal processing operation on the datafile which contains 512 msec data, when i do it on single channel its processes 512 msec,but when done in parallel for 4 channels,getting error after some iterations.

Please show us all the text displayed in red in the Command Window (and if there are any warning messages displayed in orange, please show us those too.) The full and exact text of the error message may be useful and/or necessary to determine what's going on and how to avoid the warning and/or error.

Showing a small sample of code that illustrates the problem that you're experiencing may help Answers provide a more concrete solution as well.

You can use parallel.pool.Constant -- provided that the values are read-only on the workers.

I will try this.

Thank you Walter.
