Matlab crashing on loading library

Hi!

I'm trying to interface with an USB-oscilloscope (Handyscope HS3). I got some code working last week but today every attempt to load the library required seems to cause matlab to crash. Not even the example code from the manufacturer seems to work.

Whenever I try running the code I get the message "MATLAB has encountered an internal problem and needs to close". I'm fairly certain that the problem occurs while using loadlib.

EDIT I've attached the example code I'm trying to run

This is the stack trace produced by matlab while trying to run the example from the manufacturer

Answer 1

[Ankita Nargundkar]

You can contact MathWorks technical support for further assistance.

Answer 2

[Philip Borghesani]

The crash is in the com control for the Handyscope (oscilloscope\HS3.dll). I suggest contacting support for it or starting by seeing if any demos or programs that use the scope but don't use MATLAB are still working, Then work up from there.
