Hi, all, I want to define and store a large scale arrays, like ones(3^N,1000,N) and N can be 15. However, matlab says it is out of memory, because of the large scale.

I wonder is there any way to resolve it? I mean, to fulfill the purpose but satisfy the requirement of matlab? Actually ones(3^N, 1000,1) is still very large scale.

Thanks.

Accepted answer

Does it need to be double? Can it be single, uint8, or logical instead? Will it have any values other than 1 or small integers?

Are the entries mostly zeros? Could you use the SPARSE command?

If you need to work with n-dimensional sparse arrays, there is this:
