arm_neon.h / vext_u64 (uint64x1_t __a, uint64x1_t __b, __const int __c)

[Jochen Barth]

Dear Tamar,

Sorry, I do no get the point:

>>> EXT is a byte level extract, if you have a 64 bit vector and a 64-bit
>>> type like uint64x1_t then the only possible index for n is 0.

But my previous examples with n=c=1..7 showed that different (n=c)'s are 
possible,

why is "the only possible index for n=0" ?

Kind regards, Jochen
