Hello everyone,
I have an error about parallel pool creation in Matlab (R2018b) . I'm wondering if it's could be related to a denied access but not sure. I didn't find a solution in the forum or elsewhere. Here is my error:
>> parpool('local')
Starting parallel pool (parpool) using the 'local' profile ...
Error using parpool (line 113)
Invalid default value for property 'ProcessInformation' in class 'parallel.cluster.Local':
Undefined function 'dct_psfcns' for input arguments of type 'char'
The same error occurs when I try to "validate" the pool before. I'm new in Matlab sorry if this question is not usefull.
Thank you.
Best,
Guillaume

Hi @Guillaume Carey,
The most common reason for this type of problem is some sort of setup where the MATLAB session is uable to perform any system commands.
The workaround for the situation is to create a 'startup.m' file with the following code:
setenv('MATLAB_SHELL','/bin/tcsh')
You can also look at a problem that is quite similar to yours and try a similar solution.
