Smoothing

Non-parametric regression is widely used in many scientific and engineering areas, such as image processing and pattern recognition.Non-parametric regression is about to estimate the conditional expectation of a random variable:E(Y|X) = f(X)where f is a non-parametric function.Based on the kernel...

This function can be used to obtain smooth function by increasing number of points of the function.

MOVING will compute moving averages of order n (best taken as odd) Usage: y=moving(x,n[,fun]) where x is the input vector (or matrix) to be smoothed. m is number of points to average over (best odd, but even works) y is output vector of same length as x fun (optional) is a custom function rather...

This filter could be extended into a 2D image smoothing filter. The kernel can be switched easily.This is a program to test how a gaussian filter works on a set of 1-D data ae.g. a=[1 10 1 10 1 10 1] --- use this as input or use your own 1D dataThis example uses a gaussian filter extracted from...

Figutils adds some uibuttons at the top of any figure, which allows operation on figure data, NOT requiring source data that the figures were generated with. It's a quick way to add, subtract, or average single lines or groups of lines. You can also invert, smooth (fractional octave smoothing),...
