Good catch. I think the intent was clear enough that I am not going to rerecord.

Yes, you could indeed simply convert the vector at the end with logical. But if it is going to be a logical vector, night as well create it as such.

Mostly a style issue, but if I am going to use it ten times as a logical, I might as well just create it as a logical.

I love these short videos. Sometimes they remind me of something that I had known sometime in the past, but I forgot it then… :-)

I think it is worth mentioning that it is not actually needed to change those C = 1 or C = 0 assignemnts to C = true and C = false, although it gives a nice idea of what a logical vector is. It is sufficient to call B(logical(C)) instead of B(C). The ‘logical’ function takes the double vector C full of 0s and 1s and creates a logical vector full of falses and trues. Am I right?

Just wanted to bring your attention to this: At about 2 minutes 20 seconds of the video, you do a “whos” and say “B is a double… that’s no good…”. I think you meant C there instead of B. Although this is quite obvious, and people should understand without any ambiguity, I thought I will let you know anyway, in case you wanted to correct that!

Thanks!
