Inconsistency while invoking JavaScript Method in Internet Explorer ActiveX control

Hello,

I am working on interfacing MATLAB with Google Earth Plug-in. The interface uses Internet Explorer ActiveX control as host for the Google Earth Plug-in as the plug-in uses JavaScript.

In a simple demo below (testJS.html), I successfully imitate a straight movement in Google Earth using pre-defined coordinates. (Works only on Firefox and IE, although on IE the speed is a little bit fast).

Using the same coordinates, I invoked the JavaScript methods from MATLAB script. Instead of straight movement, what I get is zig-zag movement. At first, I thought the problem was the decimal places of the input, as Google Earth supports only up to 6 decimal places. But, reducing the decimal places also brought no joy.

Does anyone have any idea what wrong is?

Thanks.

Wan.

p.s: below is the files. testJS.html is a JavaScript demo. TestOhneSimulink.m is the MATLAB code. pluginhost3.html is the host html document of the plugin.
