With the help of scipy.fft.idct() method, we can compute the inverse discrete cosine transform by selecting different types of sequences and return the transformed array by using this method.
Return value: It will return the inverse transformed array.
Example #1: In this example, we can see that by using scipy.fft.idct() method, we are able to get the inverse discrete cosine transform by selecting different types of sequences by default it’s 2.
