Understanding the vector input to matlab function dwt

Utilizing a current signal in the time domain with a 1000 points of data as my input to the dwt function [cA,cD] = dwt(x,wname), will I have to interatively use the dwt function to process across the whole dataset? Will the vector input "x" be some sort of chunck of the dataset?

Hi,

The input vector x will contain all the data points present in the input current signal.

In the below link try running the first example in MATLAB Online. Go to workspace and open the variable noisdopp to visualize the form of input vector to the function dwt
