POINT Image Point Information Function

Usage

Returns information about the currently displayed image based on a use supplied mouse-click. The general syntax for its use is

   y = point

The returned vector y has three elements:

$\displaystyle y= [r,c,v]
$

where r,c are the row and column coordinates of the scalar image selected by the user, and v is the value of the scalar image at that point. Image zoom is automatically compensated for, so that r,c are the coordinates into the original matrix. They will generally be fractional to account for the exact location of the mouse click.
