vslconvexectaskx1d / vslcorrexectaskx1d

Computes convolution or correlation for one-dimensional case with the fixed first operand vector.

Syntax

status = vslsconvexecx1d(task, y, ystride, z, zstride)
status = vsldconvexecx1d(task, y, ystride, z, zstride)
status = vslcconvexecx1d(task, y, ystride, z, zstride)
status = vslzconvexecx1d(task, y, ystride, z, zstride)
status = vslscorrexecx1d(task, y, ystride, z, zstride)
status = vsldcorrexecx1d(task, y, ystride, z, zstride)
status = vslccorrexecx1d(task, y, ystride, z, zstride)
status = vslzcorrexecx1d(task, y, ystride, z, zstride)
