[selx,sely,indexnr]=lasso(x,y);
Input: x,y - a set of points in 2 column vectors.
Output: selx,sely,indexnr - a set of selected points in 3 column vectors
Note: After the scatter plot is given, selection by mouse is started after any key press. This is done to be able to ZOOM or CHANGE AXES etc. in the representation before selection by mouse. Encircling is done by pressing subsequently the LEFT button mouse at the requested positions in a scatter plot. Closing the loop is done by a RIGHT button press.
