I am using vslsconvexec1d() to realize the convolution. However, I have several pairs of arrays, such as (x1, y1), (x2, y2)...... Before I use this function, I need to create a task descriptor. I am wondering whether I only create a task descriptor for all the array pairs in convolution. Thank you very much for your help.

Hi,

If all your arrays have the same dimensions then one task descriptor is enough.
