[x,y] = grab (axis) ¶Grab positions of landmarks on the screen.
x is the x coordinates of the points.
y is the y coordinates of the points.
axis (optional) if specified then the first 2 clicks must be on the appropriate axes. x and y (or just x if only 2 points specified ) will then be normalised.
for example:
x=grab([1 10])
the first two clicks should correspond to x=1 and x=10 subsequent clicks will then be normalized to graph units.
for example:
[x,y]=grab;
gives x and y in screen pixel units (upper left = 0,0 )
Select points by positioning the cursor over the points and clicking <SPACE>. ’q’ or <ESC> quits
