octave's plot function does not return any value, so the variable p is
undefined. Matlab returns the handles of the lines drawn. Octave does not
have handle graphics.

So, try deleting all references to p later on in the file. It might work,
although produce uglier results.

Does anyone know where I can find a working waterfall plot function?

I found one in the DAFX (ed. Zölzer, Wiley 2002) book, but I can’t for the life of me get it to work. It’s written for MatLab, so I guess there are some differences.
I get the following error:
error: value on right hand side of assignment is undefined
error: evaluating assignment expression near line 46, column 4

Line 46 is:
    p=plot3(x(1:N/2), y(1:N/2), spek(1:N/2), "k");

All the variables are defined and populated, which doesn’t preclude an undefined value coming out in the wash: but I can’t see any error in the expression. I need a hand from someone more experienced, please!

I can post the whole function if necessary.
