dualcursor2

Updated dualcursor function that displays and outputs the slope, average, and standard deviation.

This is just an update to the original dualcursor written by Scott Hirsch (http://www.mathworks.com/matlabcentral/fileexchange/2875-dualcursor).

This version displays the slope between the cursors, and calculates the average and standard deviation of all the points between the cursors.

Usage is exactly the same as the original:
dualcursor2
dualcursor2 on
dualcursor2 off
val=dualcursor2
val=[x1 y1 x2 y2 slope avg stddev]

Also uses round2, found here: http://www.mathworks.com/matlabcentral/fileexchange/4261-round2
