Dear all,
Murphy's law:
I'm very sorry, of course the proof of concept I sent to the list on
Friday contained a malicious little typo in line 52 (introduced while
cleaning up the code) not changing the result numerically but slowing
down conversion by factor 2-3. Also the conversion itself could have
been slightly optimized, however, this does no longer speed up reading,
since MATLAB's fread function is now the bottleneck. The 680 MB bdf file
is read now in about 40 s.
Best,
Andreas
