R"""(Performs a discrete cosine transform.
Parameters
----------
a : numpy.ndarray (any real type)
The input data
type : integer
the type of DCT. Must be in [1; 4].
axes : list of integers
The axes along which the transform is carried out.
If not set, all axes will be transformed.
inorm : int
Normalization type
0 : no normalization
1 : divide by sqrt(N)
2 : divide by N
where N is the product of n_i for every transformed axis i.
n_i is 2*(<axis_length>-1 for type 1 and 2*<axis length>
for types 2, 3, 4.
out : numpy.ndarray (same shape and data type as `a`)
May be identical to `a`, but if it isn't, it must not overlap with `a`.
If None, a new array is allocated to store the output.
nthreads : int
Number of threads to use. If 0, use the system default (typically governed
by the `OMP_NUM_THREADS` environment variable).
