medfilt1

1D median filtering

- - -

Calling Sequence

- -

Description

y = medfilt1(x) -Applies a 3rd order 1-dimensional median filter to input x along the -first non-zero dimension. The function appropriately pads the signal -with zeros at the endings. For a segment, a median is calculated as -the middle value (average of two middle values) for odd number -number (even number) of data points. -y = medfilt1(x,n) -Applies a nth order 1-dimensional median filter. -y = medfilt1(x,n,dim) -Applies the median filter along the n-th dimension -y = medfilt1(__, nanflag, padding) -nanflag specifies how NaN values are treated. padding specifies the -type of filtering to be performed at the signal edges.

Parameters

x: -: int | double
n: -: positive integer scalar
dim: -: positive integer scalar
nanflag: -: 'includenan' (default) | 'omitnan'
* includenan: -: Filtering such that the median of any segment
* omitnan: -: Filtering with NaNs omitted in each segment. If a segment
y: -: int | double

Examples

1) Noise supression using median filtering
-fs = 1e3;
-t =  1:1/fs:1;
-s = sin(2*%pi*2*t)+ cos(2*%pi*5*t);
-// Adding noise
-x = s + 0.1*randn(size(s));
-y = medfilt1(x);
