python - Filter numpy array if elements in subarrays are repeated position-wise in the other subarrays -

unluckily terribly similar to: filter numpy array if list within contains @ least 1 value of previous row question asked minutes ago. in case have list b = np.array([[1,2], [1,8], [2,3], [4,2], [5,6], [7,8], [3,3], [10,1]]) what want different now. i want start @ beginning of list , each subarray . want check whether element in position (with respect subarray ) encountered in position i in other subarrays . hence, removing such elements. for instance: look @ [1,2] : eliminate [1,8] cause 1 in position 0, eliminate [4,2] cause 2 in position 1. not eliminate [10,1] or [2,3] since 1 , 2 in different positions. look @ [2,3] ,eliminate [3,3] since 3 in position 1. look @ [5,6], nothing eliminate. look @ [7,8], nothing eliminate so result b = np.array([[1,2], [2,3], [5,6], 7,8], [10,1]]) my try can see in previous post tried different things. now, noticed a==b gives useful array, used filtering, can't quite decide how put together. edit: m...

vectorization - Conditional instructions in AVX2 -

can give list of conditional instructions available in avx2? far i've found following: _mm256_blendv_ * selection a , b based on mask c are there conditional multiply , conditional add, etc.? also if instructions taking imm8 count (like _mm256_blend_ *), explain how imm8 after vector comparision? avx512 introduces optional zero-masking , merge-masking instructions. before that, conditional add, mask 1 operand (with vandps or vandnps inverse) before add (instead of vblendvps on result). why packed-compare instructions/intrinsics produce all-zero or all-one elements. 0.0 additive identity element, adding no-op. (except ieee semantics of -0.0 , +0.0, forget how works exactly). masking constant input instead of blending result avoids making critical path longer, conditionally adding 1.0 . conditional multiply more cumbersome because 0.0 not multiplicative identity. need multiply 1.0 keep value unchanged, , can't produce , or andn compare...
