x

A real vector.

Default: [0]{}

datatype_icon

DCT size

The length of the DCT you want to perform. If DCT size is greater than the number of elements in x, this node adds zeros to the end of x to match the size of DCT size. If DCT size is less than the number of elements in x, this node uses only the leading DCT size elements in x to perform the DCT. If DCT size is less than or equal to zero, this node uses the length of x as the DCT size.

datatype_icon

DCT {x}

The DCT of x.

error

A value that represents any error or warning that occurs when this node executes.
