filter_median (MathScript RT Module Function)
Owning Class: filter implementation
Requires: MathScript RT Module
Syntax
y = filter_median(x)
y = filter_median(x, n)
Legacy Name: medfilt1
Description
Applies a one-dimensional median filter of order n.
Inputs
| Name | Description |
|---|---|
| x | Specifies the input signal. |
| n | Specifies the order of the filter. If n is odd, y(k) is the median of x(k-(n-1)/2 : k+(n-1)/2). Otherwise, y(k) is the median of x(k-n/2 : k+n/2-1). For the edge points, LabVIEW assumes zeros to the left and right of x. The default is 3. |
Outputs
| Name | Description |
|---|---|
| y | Returns the filtered signal. |
Examples
A = magic(6);
B = filter_median(A, 3)
