Memory overload with dec2bin
显示 更早的评论
If i try to run this command:
M = dec2bin(0:2^21-1, 21);
I get the following error: "Error using * Out of memory. Type HELP MEMORY for your options."
When trying to run it with 2^20 it still works.
Is there a way to work around that error?
PS: I will have to work with that data later on. Is that even possible?

This creates the vector 0:2^21-1 as double array at first, which requires 16.777.216 Bytes. Then for each of these values 21 characters a 2 Byte are created, which means additional 88.080.384 Bytes. If this exhausts your memory already, you simply do not have enough RAM. Then either use something like FEX: VChooseKRO to create the output as UINT8 array, which occupies the half size only:
M = VChooseKRO(uint8([0, 1]), 21);
But a much better idea would be to run a 64-bit Matlab version on a 64-bit operating system an installing some more GB of RAM.
