How to do vector element-wise division?

[liang xiang]

Hi, I want to use blaze vector to do division like this:

using blaze::CustomVector;
using blaze::aligned;
using blaze::unpadded;
using blaze::rowVector;
typedef CustomVector<float,aligned,unpadded,rowVector>  AlignedUnpadded;
int vsize = 10;
std::vector<float> b(vsize, 1), a(vsize, 2), c(vsize, 0);
AlignedUnpadded bb(&b[0], vsize);
AlignedUnpadded ba(&a[0], vsize);
AlignedUnpadded bc(&c[0], vsize);
bc = bb / ba;

But in compilation: error: no match for ‘operator/’ in ‘bb / ba’ /home/lxiang/Downloads/blaze-2.6/blaze/math/intrinsics/Division.h:232:36: note: candidates are: blaze::simd_cdouble_t blaze::operator/(const blaze::simd_cdouble_t&, const blaze::simd_double_t&) /home/lxiang/Downloads/blaze-2.6/blaze/math/intrinsics/Division.h:204:35: note: blaze::simd_cfloat_t blaze::operator/(const blaze::simd_cfloat_t&, const blaze::simd_float_t&) /home/lxiang/Downloads/blaze-2.6/blaze/math/intrinsics/Division.h:140:35: note: blaze::simd_double_t blaze::operator/(const blaze::simd_double_t&, const blaze::simd_double_t&) /home/lxiang/Downloads/blaze-2.6/blaze/math/intrinsics/Division.h:112:34: note: blaze::simd_float_t blaze::operator/(const blaze::simd_float_t&, const blaze::simd_float_t&)

Can you help me?

Thanks, Liang

Hi!

Vector division has been introduced in Blaze 3.0 (see the notes in the release archive). From the compiler output I can see that you are currently using Blaze 2.6. Please update (if possible) to the current release or alternatively clone the repository to enable vector division. I hope this explanation helps. Thanks for raising this issue,

Best regards,

Klaus!
