Y = DCTN(X) returns the discrete cosine transform ...

Y = DCTN(X) returns the discrete cosine transform (DCT) of X.
X = IDCTN(Y) returns the inverse_discrete cosine transform (IDCT) of Y.
Y = DSTN(X) returns the discrete sine transform (DST) of X.
X = IDSTN(Y) returns the inverse discrete sine transform (IDST) of Y.
X and Y can be N-dimensional.
D = DSTMTX(k) returns the k-by-k DST transform matrix.
For more information, enter "help dctn", "help dstn", "help idctn", "help idstn" and "help dstmtx" in the matlab command window (console).
