Hi 克,
I understand that when you execute your code your server memory is running out of space. This issue is because you are using a "parfor" loop inside a for loop, due to this the amount of data transferred will be much greater and you will also not notice any major computational benefit when compared to nested-for loops. This happens because each of the multiple “parfor” executions incurs an overhead.
To solve this issue run the outer loop in parallel instead of the inner loop, this will ensure that the overhead incurs only once. For more information on the same, kindly refer to the following documentation -
I hope this provides you with the required information regarding your query.
Thank you,
Shushant
