Hi, I have a quality flag that I want to convert to binary to create a binary mask. The QF is 7200x3600 int16.

I saw that some people were using: dec2bin(typecast(int16(QF),'unit16'))

but I get an error, because for using typecast the data has to be a vector.

I could reshape the data, convert it and then reshape it back to its original size, but I was wondering if there is a way to do it in just one step.

Thanks

Reshaping is fast since it uses a shared data copy instead of a deep data copy. So your three step process isn't going to be slowed down much by it.
