Iteration Speed issue when Indexing 3D array wried to a while-loop

[Shein]

Hi,

I wanted to have both independencies and continuities of 14 random number generations.  That's why I can chose any different seeds to start with (during 1st call) but set the seeds to -1 for the continuous generations.  (i.e., 10 to 23 seed values that I chose can be different combination unless non-repeated).  Am I answering your question?

Regards,

Shein

Hi all,

Woule you think that the iteration-speed limitation I have is due to wiring a huge size of 3D array (larger numbers of pages) to a while-loop and indexing it? If so, how would you deal with this problem?

Thanks in advance,

Shein

A am pretty sure it's not the indexing operation itself, but the further processing you do with the output of the indexing operation and all other operations that depend on the size of the indexed slice (which of course is proporionally larger).

For example you create 14 gaussian noise traces per loop iteration, each with 10000+ elements. This alone costs about 50ms on my PC.
