jax.scipy.fft.idctn

jax.scipy.fft.idctn(x, type=2, s=None, axes=None, norm=None)

Computes the multidimensional inverse discrete cosine transform of the input

JAX implementation of scipy.fft.idctn().

Parameters:

• x (Array) – array

• type (int) – integer, default = 2. Currently only type 2 is supported.

• s (Sequence[int] | None) – integer or sequence of integers. Specifies the shape of the result. If not specified, it will default to the shape of x along the specified axes.

• axes (Sequence[int] | None) – integer or sequence of integers. Specifies the axes along which the transform will be computed.

• norm (str | None) – string. The normalization mode. Currently only "ortho" is supported.

Returns:

array containing the inverse discrete cosine transform of x

Return type:

Array
