I try to Write/Read Binary files, and the results are extremely slow.
For exemple, for the same array of "double", it takes 70 seconds with
Experimental`BinaryExport compared to .4 second in IDL (approximately
same time in C). I cannot believe mathematica cannot do that faster !
I am working with mathematica 4 on windows.
I have tried Experimental`BinaryExport and also the "fast binary"
package from mathsource, which is a little faster (3 times faster, but
it is still extremely slow!)
I use :
BinaryExport["c:\path\filename",Flatten[data],{Real64"..}]
Can someone help me ??
Thanks,
Rémi
