31   ZOOMFIXTICKS(FIG) operates on the figure with handle FIG.
32   ZOOMFIXTICKS(AX) operates on the figure with child AXES handle AX.
33   ZOOMFIXTICKS with no arguments operates on the current figure.
34
35   Note that when using this function, you will need to modify the FIXTICKS
36   subfunction to meet your application needs.  Alternatively, you can comment
37   out the function and supply it as an M-file function on the MATLAB path. 
38   If you supply your own, make sure that the M-file is named &quot;fixticks.m&quot;, and
39   it takes a single input argument, the handle to an AXES object.
40
41   Example:
42       hf = figure;
43       xdata = [0:.01:1];
44       ydata = 100000*sin(2*pi*5*xdata);
45       plot(xdata,ydata);
46       zoomfixticks(hf)
