v256 Vector
Blend packed double-precision (64-bit) floating-point elements from a and b using mask, and store the results in dst.
____ VBLENDVPD ymm1, ymm2, ymm3/v256, ymm4 Conditionally copy each quadword data element of double-precision floating-point value from the second source operand (third operand) and the first source operand (second operand) depending on mask bits defined in the mask register operand (fourth operand).
