[Eeglablist] DEL2MAP

[Luis Garcia Dominguez]

Hello everybody,

I am using the DEL2MAP function to convert the current eeg montage to
laplacian, but noticed the function is pretty slow when fed with data
matrices, in my computer a segment of 32-by-200 runs in about 10 sec.
The bottleneck seems to be in the function GDATAV4 that is called by
GRIDDATA, in particular a double FOR-cicle inside that function. Have
any of you consider the vectorization of that function or any other
way to improve speed?

Thanks
