How do I shift index and keep it as logical?

I have a index Status as logical and I want to shift it to one row up and one row down as different index array to use for comparison and plotting. I use the following commands:
Last=[NaN;Status(1:end-1)];
Next1=[Status(2:end);NaN];
It creates two new variables, but they become "double", instead of keep them as logical array. Appreciate any help on this.

Can you show the code that generates Status and uses Last and Next1? Just need to see how the logical indices are being used. Also, a logical index cannot store a NaN value. That's why Last and Next1 are being casted to double matrix instead.

Logical values can only be 0 or 1. NaN values can only be kept in double or single class variables. You need to come up with a different scheme for whatever you are doing. Will using false instead of NaN work for your downstream code?

thanks, replacing NaN with "false" works nicely!
