MATLAB: How to zoom in/out on an axis programmatically

In a figure window toolbar, there are spyglass icons that let you zoom in and out on parts of an image or plot. I'd like to know how to do this programmatically.

There is a function "zoom" with the following options :

 zoom on 
 zoom off
 zoom out

 zoom xon

 zoom(factor)
 zoom(fig, option)

MATLAB: How to disable Zoom and Pan in the post action callback

To enable the ability to turn off pan or zoom in the post action callback, you must set the "ModeHandle" 's "Blocking" property to false. This feature is undocumented and is not even visible when the property 'hideundocumented' is set to 'off'.

For "zoom": Use the following code in the post action callback to turn off the zoom using the set function:

function myzoompostcallback(obj,evd)
%obtain zoom object from figure
hZ = zoom(obj);
%turn blocking off to allow setting the zoom state (true by default)
hM = hZ.ModeHandle;
set(hM,'Blocking',false);
%turn zoom off
set(hZ,'Enable','off');

Use the following code in the post action callback to turn off the zoom using dot notation:

function myzoompostcallback(obj,evd)
hZ = zoom(obj);
hZ.ModeHandles.Blocking = false;
hZ.Enable = 'off';

For "pan":

Use the following code in the post action callback to turn off the pan using the set function:

function mypanpostcallback(obj,evd)
%obtain pan object from figure
hP = pan(obj);
%turn blocking off to allow setting the pan state (true by default)
hM = hP.ModeHandle;
set(hM,'Blocking',false);
%turn pan off
set(hP,'Enable','off');

Use the following code in the post action callback to turn off the pan using dot notation:

function mypanpostcallback(obj,evd)
hP = pan(obj);
hP.ModeHandles.Blocking = false;
hP.Enable = 'off';
