Passing PipeArray as template in functor

Hi, I tried running the code in couple other environments, but I am still having the same error with the code.

I am trying to pass the pipe array to a function or a functor.

I do not want to define the pipe array globally as in the sample above.

I have checked some of the samples using pipes as my intention (such as: https://github.com/oneapi-src/oneAPI-samples/blob/master/DirectProgramming/C%2B%2BSYCL_FPGA/ReferenceDesigns/matmul/src/matmul.hpp )

The pipe defined in line 93 is the type of pipe I want to implement, but in pipe array instead of pipe.

Is there any samples that defines and passes pipe array instead of pipe to another function or a functor?
