Description
This function is declared
in
.mkl_vsl_functions.h
The function routine changes the value of the parameter
mode
for the operation of convolution or correlation. This parameter defines whether the computation should be done via Fourier transforms of the input/output data or using a direct algorithm. Initial value for mode
is assigned by a task constructor.Predefined values for the
mode
parameter are as follows:Value | Purpose |
|---|---|
VSL_CONV_MODE_FFT | Compute convolution by using fast Fourier transform. |
VSL_CORR_MODE_FFT | Compute correlation by using fast Fourier transform. |
VSL_CONV_MODE_DIRECT | Compute convolution directly. |
VSL_CORR_MODE_DIRECT | Compute correlation directly. |
VSL_CONV_MODE_AUTO | Automatically choose direct or Fourier mode for convolution. |
VSL_CORR_MODE_AUTO | Automatically choose direct or Fourier mode for correlation. |
