I'm afraid that I am no great expert with PCs running Windows (only
use it for PowerPoint and trying to troubleshoot spm related problems
on PCs). Our PCs that run Windows have Matlab 6.1 installed on them,
so the spm_hist2.dll file was compiled using Matlab 6.1. It may not
work when called from within the older Matlab 5.x.
If you have a C-compiler installed on your PC, then you could try
compiling the function by changing to the SPM directory and typing the
following in Matlab:
mex spm_hist2.c -O
Alternatively, some kind soul out there who has Matlab 5.3 and a C compiler
installed on their PC may wish to do the job for you.
Best regards,
