Ever have some data that might have some NaN values? And you start doing computations with these data, expecting |NaN|s to propagate... Only to find later, that the |NaN|s... 더 읽어보기 >>

I've been exploring some older functions in MATLAB recently and trying to characterize them. The function diff is one of them. And I realized it has a really unusual behavior when the... 더 읽어보기 >>

Yes, I know, data are, but the title just sounded terrible that way. Ever wonder what data you have stored in some files, particularly MATLAB MAT-files? Sometimes I'd... 더 읽어보기 >>

My last post started the discussion about how to ensure data values met certain constraints. The solutions I talked about were ones where you checked at certain places during a... 더 읽어보기 >>

Do you sometimes need to be sure an array has only bounded, positive values? At least one customer asked about this recently and noted that it could be quite involved. ... 더 읽어보기 >>

After reading last week's post on calculating with empty arrays, one of my colleagues mentioned some other behaviors with empty arrays that have tripped him up in the past.... 더 읽어보기 >>

MATLAB has had empty arrays since before I started using the program. When I started, the only size empty array was 0x0. When version 5 was released, empty arrays came along for the... 더 읽어보기 >>

There are so many functions in MATLAB that sometimes users think that if they can't find the function they are thinking of, it's because they don't know the name. Sometimes... 더 읽어보기 >>
