I think DCT in matlab using radian. Because the syntax for degree is cosd. When you see the algorithm in https://www.mathworks.com/help/images/discrete-cosine-transform.html#:~:text=The%20discrete%20cosine%20transform%20(DCT,(DCT)%20of%20an%20image, the formula using pi. We know pi is used for radian
