Discrete cosine transform

`y = dct(x)`

`y = dct(x,n)`

`y = dct(x,n,dim)`

`y = dct(___,'Type',dcttype)`

specifies
the type of discrete cosine transform to compute. See Discrete Cosine Transform for details. This option can be combined with
any of the previous syntaxes.`y`

= dct(___,'Type',`dcttype`
