Level 1 BLAS functions
NOTES:
* destination and source should NOT overlap
* stride is assumed to be positive, but it is not
assert'ed within function
* conj_src parameter specifies whether complex source is conjugated
before processing or not. Pass string which starts with 'N' or 'n'
("No conj", for example) to use unmodified parameter. All other
values will result in conjugation of input, but it is recommended
to use "Conj" in such cases.
