hi all,
i get out of memory errors when running a complex image processing task in matlab.
checking the memory command:
>> memory
Maximum possible array: 3434 MB (3.600e+09 bytes) *
Memory available for all arrays: 3434 MB (3.600e+09 bytes) *
Memory used by MATLAB: 1129 MB (1.184e+09 bytes)
Physical Memory (RAM): 16158 MB (1.694e+10 bytes)
...so i have 16gb installed on my system --> correct
but matlab is only allowed to use 3.4gb? how can i change that?
first thought: did i only install a 32bit version of matlab?
>>ver
-----------------------------------------------------------------------------------------------------
MATLAB Version: 9.3.0.713579 (R2017b)
MATLAB License Number: removed ;-)
Operating System: Microsoft Windows 10 Enterprise Version 10.0 (Build 17763)
Java Version: Java 1.8.0_121-b13 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode
-----------------------------------------------------------------------------------------------------
MATLAB Version 9.3 (R2017b)
and the mexext command:
>> mexext
mexw64
so it is 64bit, and i cannot use all my memory?
how can i fix that?
thanks
alex

Hi,
This can be possible if you have set a limit on MATLAB array size limit with less than 100%. You can see the following documentation to update that setting and this should clear out the query.
Also this discussion can be useful.

hi,
thanks for the reply - i think there was a problem with windows running out of disk space, which caused many problems. since i cleaned up the disk and restarted the system it runs as it did before...
thanks
alex
