[Insight-users] problem running ITK registration program from within Matlab

[pinpress]

Koen,

I think somehow you probably misunderstood me -- the ITK registration
programs are not mex files to run from within Matlab. Instead, they are
compiled using Cmake and make and they run as an executable on the shell.
Because cmake and make link the executable dynamically against all the
necessary shared libraries at run time, it has to know where to look for the
right libraries, either at command prompt or from Matlab if you want it to
run from within. 

Yes, exactly that I used "unix(command_line)" type of call from Matlab,
where "command_line" is the compiled ITK program. 

So, can you post where your libstdc++ libraries are located on your system,
either the one comes with the system, or the Matlab version? I may do some
more digging (e.g., create symbolic link to point to the right ones) if I
know where they are.

Since I did not really use mex file, sorry that I can't answer your question
regarding image array. 

thanks. pinpress
