I noticed a severe error in ParforProgress2 when closing/reopening the matlabpool during a MATLAB (R2013a) session:

Try something like

matlabpool open local
ParforProgressStressTest2
matlabpool close
matlabpool open local
ParforProgressStressTest2
matlabpool close

While the first call of ParforProgressStressTest2 works without problem, the second call errors out with

Warning: While loading an object of class 'ParforProgress2':
Undefined variable "ParforProgressClient2" or class "ParforProgressClient2.createClient".

Afterwards one has to close and restart MATLAB in order to make ParforProgress2
work again.
I assume this issue is new to MATLAB R2013a, maybe related to #1?

Would be cool if this could be fixed! Hope this is not an issue in MATLAB itself?

I have used this great tool for some time but it appears to not work in 2014a with the following error. Works on same exact code in 2013b. Please update, this is the nicest parfor progress meter I have found!

Warning: While loading an object of class 'ParforProgress2': Undefined variable "ParforProgressClient2" or class "ParforProgressClient2.createClient". Warning: The following error was caught while executing 'ParforProgress2' class destructor: Attempt to reference field of non-structure array. Error using ParforProgress2/increment (line 121) Attempt to reference field of non-structure array.

I'm happy to receive any feedback from those of you working with globals.

I started receiving this today when trying to run parametric sweeps and the progress bar. No changes in my code or yours. There may have been a Java update since last use.

Matlab is 2013a
Java 7 U 51
OS Win 8 64bit (not 8.1)

Error is:

Unknown error while initializing "ParforProgressStarter2": 
     Undefined variable "ParforProgressServer2" or class "ParforProgressServer2.createServer". 
Undefined function or variable 'nbr_files'.

Please let me know what else I can provide to help diagnose. The call to ParforProgressStarter2 is

ppm = ParforProgressStarter2('Parametric Sweep: RSI with RAVI Transformer', row, 0.1, show_debug, run_javaaddpath);

Values for variables are confirmed as:

row = 1140480
show_debug = 0
run_javaaddpath = 0

Thanks,
Mark

Trying to execute ParforProgressStressTest2 with MATLAB R2013a gives an error.

Typing:

matlabpool open
ParforProgressStressTest2

outputs:

Warning: While loading an object of class 'ParforProgress2':
Undefined variable "ParforProgressClient2" or class "ParforProgressClient2.createClient".
Warning: The following error was caught while executing 'ParforProgress2' class destructor:
Attempt to reference field of non-structure array.
Warning: While loading an object of class 'ParforProgress2':

  >> execution time was 0.64s.

Error using ParforProgress2/increment (line 121)
Attempt to reference field of non-structure array.

There is no error without the matlabpool command, or using R2012b.
