double dot ( VBase4D const other )

fill ( double fill_value )

Sets each element of the vector to the indicated fill_value.

This is particularly useful for initializing to zero.

VBase4D fmax ( VBase4D const other )

generateHash ( ChecksumHashGenerator hashgen )

Adds the vector to the indicated hash generator.

generateHash	(	ChecksumHashGenerator	hashgen,
