Convolution and Correlation Task
Constructors
Task constructors are routines intended for creating
a new task descriptor and setting up basic parameters. No additional parameter
adjustment is typically required and other routines can use the task object.

implementation of the convolution and correlation API provides two different
forms of constructors: a general form and an X-form. X-form constructors work
in the same way as the general form constructors but also assign particular
data to the first operand vector used in the convolution or correlation
operation (stored in array
x
).
Using X-form constructors is recommended when you
need to compute multiple convolutions or correlations with the same data vector
held in array
x
against
different vectors held in array
y
. This helps
improve performance by eliminating unnecessary overhead in repeated computation
of intermediate data required for the operation.
Each constructor routine has an associated
one-dimensional version that provides algorithmic and computational benefits.
If the constructor fails to create a task
descriptor, it returns the
NULL
task pointer.
