hi,
I have successfully written my first test program in matlab, it works
perfectly except the display is not quite right, to the left and write
of the plotted data there are blank areas with nothing on, how can i get
rid of these a link to the image is attached, and the code is below.
hope someone can tell me what i am doing wrong.
