Hi, all,
I defined an array like S=ones(N,x,'uint32'). And I give values to all of them. However I find out the maximum value is 65535 which is 2^16 not 2^32.
I tried 'uint64' but the limit is still 65535, why is that?
Thanks.

Oh, when I use class, it is converted to uint16. I need to figure out why?
However I only define uint32 at the beginning. So what could be a reason for converting to uint16? I am confused.

Calling class() causes no conversion. It must have got converted some other way.

Somewhere along the way, you must have converted it to uint16, perhaps without realizing that you did so.

Thanks, Walter. I think it somewhere convert to double, however, double is more than uint32, right? Does it matter?

Now, I shut all programs off and restart it, seems that there is no such convert data type problems.
