回答： Or Hirshfeld 2015-4-26

I'm trying to load dll library of commands in order to connect to software api but when i load it i got errors although previous versions of the api and software did work

I tried in Matlab 32bit and it worked but in matlab 64bit it doesn't

my code is

    addpath('C:\Program Files\OptiTrack\Motive\lib'); % change if necessary
    addpath('C:\Program Files\OptiTrack\Motive\inc'); % change if necessary
    [notfound,warnings]=loadlibrary('NPTrackingTools','NPTrackingTools.h')

in "lib" folder you can find 2 dll's "NPTrackingTools.dll" and "NPTrackingToolsx64.dll" and 2 lib files "NPTrackingTools.lib" and "NPTrackingToolsx64.lib"

in "inc" folder you can find 2 header files "NPTrackingTools.h" and "trackablesettings.h" i attached them as text files

I'm using win7 64bit with matlab 2014a 64 bit i tried different mex compilers: Microsoft Windows SDK 7.1 (C++) and Microsoft Visual C++ 2013 Professional. but got the same errors.

more background information: I'm trying to close loop of control system that get position of Quad-copters from Optitrack cameras and Motive software. i already succeed connecting throw NatNet interface API in Simulink but failed on using in Real-Time Windows Target and matlab support told me it's problematic to implement in Real-time mode Simulink because this API use .NET DLL so now I'm trying to make the other API to work because it's normal DLL and not .NET.

the errors i got is

Error loading library intermediate output follows.
The actual error is at the end of this output.

There is many problem with the header so it need to be edit

see the solution on GitHub and MatlabCentral

Those header files contain c++ classes which are not supported by loadlibrary. I very much doubt they worked or would work using loadlibrary with 32 bit MATLAB. You will need to find a C interface you can use or write a mex file.
