skewness

skewness(
o_waveform
)
=> n_skewness / nil

Description

Calculates the skewness of the specified waveform.

Skewness is a measurement of symmetry or, more precisely, the lack of symmetry. A perfectly symmetric waveform has a skewness value of zero.

Arguments

o_waveform

Waveform whose skewness is to be calculated.

Value Returned

n_skewness	Skewness value of the specified waveform.
nil	Skewness value cannot be calculated because of an error.

Examples

The following example opens simulation results stored in the specified directory.

openResults("/servers/user/distribution.psf")

=> "/servers/user/distribution.psf"

The following example lists the results contained in the results directory.

results()

=> ("tran")

The following example selects the tran results of the results directory.

selectResults('tran)

=> stdobj@0x2a9de759

The following example creates a waveform object for the signal v1net stored in the tran results.

waveform=v("v1net" ?result "tran")

=> srrWave:0x3232c020

The following example calculates the skewness value of the specified waveform.

skewness(waveform)

=> 0.1106943
