Description
The
vslConvSetInternalPrecision
/
vslCorrSetInternalPrecision
routine changes the value of the parameter
internal_precision
for the operation of convolution or correlation. This parameter defines whether the internal computations of the convolution or correlation result should be done in single or double precision. Initial value for
internal_precision
is assigned by a task constructor and set to either "single" or "double" according to the particular flavor of the constructor used.
Changing the
internal_precision
can be useful if the default setting of this parameter was "single" but you want to calculate the result with double precision even if input and output data are represented in single precision.
Predefined values for the
internal_precision
input parameter are as follows:

Value
Purpose
VSL_CONV_PRECISION_SINGLE
Compute convolution with single precision.
VSL_CORR_PRECISION_SINGLE
Compute correlation with single precision.
VSL_CONV_PRECISION_DOUBLE
Compute convolution with double precision.
VSL_CORR_PRECISION_DOUBLE
Compute correlation with double precision.
