Details:

in Cygwin 1.7.9 (a recent fresh install including Octave-3.4.0 and
GraphicMagick-1.3.12)

Running the following commands:


M=randi([0 256],100,100);
imwrite(M,,jet(256),'image.jpg','jpg')


OR


M=randi([0 256],100,100);
imwrite(M,[1 1 1; 0 0 0],'image.jpg','jpg')


Produces the following error, which does not occur in MATLAB:


error: ind2rgb: subscript indices must be either positive integers or
logicals
error: called from:
error:   /usr/share/octave/3.4.0/m/image/ind2rgb.m at line 63, column 5
error:   /usr/share/octave/3.4.0/m/image/imwrite.m at line 176, column 16
