With the help of scipy.fft.dct() method, we can compute the discrete cosine transform by selecting different types of sequences and return the transformed array by using this method.
Return value: It will return the transformed array.
Example #1: In this example, we can see that by using scipy.fft.dct() method, we are able to get the discrete cosine transform by selecting different types of sequences by default it’s 2.
[20.00000000 -6.30864406 0.00000000 -0.44834153]
Example #2 :
[ -0.50866619 -0.58578644 -0.79439535 -1.34919819 -3.41421356 -29.34774027]
