   <title>Description</title>
   <para>
This function computes the Fast Hartley Transform (FHT) of the input signal `D`.
If D is a matrix, the Hartley transform is calculated along the columns by default.
If N is specified, the first N elements along the specified dimension are used for the transform.
If DIM is specified, the transform is calculated along the specified dimension.
