| Indeed, you are right. The plot worked when image size was reduced.
But, pray, why this restriction in Octave/gnuplot? Matlab has no such problems.
Thank you so much for the very prompt response.
Best,

Simple plots are working and, so, Octave and gnu plots are linked up.

The image you're trying to display is 176259x100 pixels. This is creating a problem for gnuplot (not gnu plot, as gnuplot is not a GNU project). If you reduce the image size by ... a = s(1:100:k2,1:100); ... then it should work. Ben
