I am using Matlab R2013a with Parallel Computing Toolbox:
>> ver
-------------------------------------------------------------------------------------------------
MATLAB Version: 8.1.0.604 (R2013a)
MATLAB License Number: XXXXXX
Operating System: Microsoft Windows 7 Version 6.1 (Build 7601: Service Pack 1)
Java Version: Java 1.6.0_17-b04 with Sun Microsystems Inc. Java HotSpot(TM) 64-Bit Server VM mixed mode
-------------------------------------------------------------------------------------------------
MATLAB Version 8.1 (R2013a)
.....
Parallel Computing Toolbox Version 6.2 (R2013a)
.....
I was trying to run a parallel pool locally employing parpool('local') command, and got error message:
>> parpool('local')
Undefined function 'parpool' for input arguments of type 'char'.
Apparently, Matlab can not find this function:
>
> which parpool
'parpool' not found
I checked a current search path. The Parallel Computing Toolbox was there:
>> path
MATLABPATH
....
C:\Program Files\MATLAB\R2013a\toolbox\distcomp
C:\Program Files\MATLAB\R2013a\toolbox\distcomp\distcomp
C:\Program Files\MATLAB\R2013a\toolbox\distcomp\user

C:\Program Files\MATLAB\R2013a\toolbox\distcomp\array
C:\Program Files\MATLAB\R2013a\toolbox\distcomp\pctdemos
...
So, I am wondering, how to fix this issue.
Can someone help me?

Dimitri

PARPOOL was introduced in R2013b to replace MATLABPOOL. In R2013a and earlier, use MATLABPOOL.
