I think that depends upon compatibility in other areas.

Trusting my memory, plot3 (<real_matrix>, <real_matrix>,  
<real_matrix>) produces a series of 3D lines in Matlab, but produces a  
single line in Octave ... the Octave result will zig-zag (see the code  
below)

	 [x, y] = meshgrid (0:10, 0:10);
	 z = x.*y;
	 figure(1)
	 clf
	 plot3 (x, y, z)

Same for plot3 (<real_matrix>, <complex_matrix)

	 y = y + 1i*z;
	 figure(2)
	 clf
	 plot3 (x, y)

This issue is what I think needs attention, and I have a faint  
recollection that maintaining the complex_vector/matrix feature was  
problematic.
