MKL problems running vslzCorrExec1D, cross correlation.

I can't run vslzCorrExec1D because I get status=-2303 or -2302.

Here is my code:

 

 

    // Creating input and output vetcors
    std::vector<std::complex<double>> x, y, z;
    x.resize(5);
    y.resize(5);
    z.resize(2*std::max(x.size(),y.size()) - 1);

    // Starting MKL cross correlation 
    VSLCorrTaskPtr task;
    int status = 0;
    int iy0 = y.size() - 1;
    status = vslzCorrNewTask1D(&task, VSL_CORR_MODE_AUTO, y.size(), x.size(), z.size());
    status = vslCorrSetStart(task,&iy0);
    status = vslzCorrExec1D(task, (MKL_Complex16*)y.data(), xyz_indx, (MKL_Complex16*)x.data(), xyz_indx, (MKL_Complex16*)z.data(), xyz_indx);

 

 

Where are errors?

Hi,

 

Thanks for reaching out to us.

 

>>Where are errors?

 

Could you please try changing the below line as follows?

 

int iy0 = y.size() - 1;

 

to

int iy0 = -(y.size() - 1);

 

Please refer to the below link for details about the start parameter while using the vslCorrSetStart routine.

Please try running your code with the above changes and do let us know if it resolves your issue. If not, please provide us a complete reproducer with oneMKL version and your OS details so that we can work on it from our end.

 

Regards,

Vidya.
