Description
To use vdsp, DSPSplitComplex seems to be needed according to documents
To use blas package, DSPComplex will be needed according to this discussion
to achieve to support complex type, using DSPComplex is ideal?
I must check the difference between DSPComplex and DSPSplitComplex at first.
DSPComplex is the consecutive float values.
Complex data are stored as ordered pairs of floating-point numbers. Because they are stored as ordered pairs, complex vectors require address strides that are multiples of two.

On the other hand, DSPSplitComplex is stored in different memories
A structure that represents a single-precision complex vector with the real and imaginary parts stored in separate arrays.

So I need to implement the function to connect this difference of memory layout
