2 | %MYGINPUT Graphical input from mouse with custum cursor pointer.

4 | % the X- and Y-coordinates in length N vectors X and Y.
|

5 | %
|

6 | % [X,Y] = MYGINPUT(N, POINTER) also specifies the cursor pointer, e.g.

|

8 | % in Matlab's documentation to see the list of available pointers.

9 | %
|

10 | % MYGINPUT is strictly equivalent to Matlab's original GINPUT, except
|

11 | % that a second argument specifies the cursor pointer instead of the
|

12 | % default 'fullcrosshair' pointer.
|

14 | % Example:
|
---|
15 | % plot(1:2,1:2,'s');
|

16 | % hold on
|
---|
17 | % [x,y] = myginput(1,'crosshair');
