IDCT
Inverse discrete cosine transform (IDCT) of the input signal.
blockType: IDCT

Path in the library: |
Description
Block IDCT calculates the inverse discrete cosine transform (IDCT) of the input signal . If the input signal is a matrix on , the block calculates the IDCT transformation of each channel in the matrix.
Ports
Input
#
IN_1
—
The input signal
vector | the M by N matrix | array
Details
Specify the input signal in the form of a vector, matrix on or an array.
For all input arrays, the block calculates IDCT transformations based on the first dimension. The size of the first dimension (the frame size) must be a power of two. To work with other frame sizes, use the block Pad to fill or truncate the frame size to a length equal to a power of two.
If the input signal for the block is IDCT is the matrix on , the block treats each input column as an independent channel containing consecutive samples.

The output IDCT is a converted signal
vector | the M by N matrix | array
Details
The output IDCT is a transformed signal in the form of a vector, matrix on or an array.
If the block outputs a matrix on Then The -th column of the matrix contains the length the corresponding input column.
