Description

locate is used to get the coordinates of one or more points selected with the mouse in a graphics window. The coordinates are given using the current graphics scale.

If n>0, n points are selected and their coordinates are returned in the matrix x.

If n<=0, points are selected until the user clicks with the left button of the mouse which stands for stop. The last point (clicked with the left button) is not returned.

x=locate() is the same as x=locate(-1).

If flag=1 a cross is drawn at the points where the mouse is clicked.
