File Information
Description

EZSMOOTHN provides a fast, automatized and robust discretized spline smoothing for real or complex data of arbitrary dimension. EZSMOOTHN can deal with missing data.
Z = EZSMOOTHN(Y) automatically smoothes the uniformly-sampled array Y. Y can be any real or complex N-D array. Non finite data (NaN or Inf) are treated as missing values.

EZSMOOTHN is an easy and simplified version of the SMOOTHN function. It contains around 40 lines of code to make the understanding of SMOOTHN much easier.

Enter "help ezsmoothn" in the Matlab command window for complete instructions and 1-D to 3-D examples.
