% In the case that a session got created we evaluate the error further

if ( instr_session ~= 0 )

[errCode, errMsg] = calllib( vxipnpLib, 'rsspecan_error_message',

instr_session, err, errMsg );

errString = sprintf('%s', char(errMsg));

disp( errString );

errMsg = '';

[DummyErr, errCode, errMsg] = calllib( vxipnpLib,

'rsspecan_error_query', instr_session, errCode, errMsg );

errString = sprintf('%d: %s', errCode, char(errMsg));

disp( errString );

% ... and we must make sure to disconnect from this device !

alllib( vxipnpLib, 'rsspecan_close', instr_session );

3.10 Known Problems

"A 'Selected' compiler was not found. You may need to run mex -setup"

To successfully load a library using the loadlibrary functionality the default compiler

needs to be set up in MATLAB. The supported compilers of the currently available

releases are listed here:

http://www.mathworks.de/support/compilers/current_release/win32.html

and here:

http://www.mathworks.de/support/compilers/current_release/win64.html

In this application note the Microsoft® Visual C++® 2008 SP1 V9.0 Professional

Edition compiler was used. Especially on MATLAB 64-bit installations a non-MATLAB

compiler needs to be set configured manually.
