function outdots = manual_calibrate(screenNum, [dots])
View all dots, calibrate manually. This function can be used either
to update the global variables XCALIBDOTS YCALIBDOTS, or to modify the
locations of a specific subset of dots. The first is what happens if
the function is called without the "dots" argument, and the second is
what
happens if it is called with this argument.
Input:
screenNum scalar, equal to 1 (left screen) or 2 (right screen)
dots
Nx2 array of floating point numbers, [x y] These are
dotcenters in screen
pixel coordinates. This argument is optional. If omitted the function
modifies XCALIBDOTS and YCALIBDOTS.
Output:
outdots: same structure as dots.
