Usage Syntax: dct(object=VAL, axis=[x][y][z], dir=[1/-1]) The dct() function computes the forward or inverse discrete cosine transform of values along one or more axis. If no axis is specified, then all the computation is performed along all three axis. If the direction is not specified, a forward dct is assumed. The dct() function always returns a DOUBLE.
Examples dv> # This example computes the dct along the X and Y axis, producing an array with the same Z dimension of the input data. dv> a = dct(object=data, axis=xy) |
