I wasn't aware there is a difference. Thought that octave treated a real-type zero as a boolean.

If you want, you can explicitly cast z1 to a logical:

z2( logical(z1) ) = 1

I assume this makes an intermediate "copy" of z1 even if the logical version is not written to? i.e. logical(z1) isn't just a different "view" of the z1 data array.
