Correlation and covariance (Correl, CoVar)

Correl

Correl('Expression1','Expression2')

Arguments

'Expression1/2'

Signals or expressions for which to calculate the correlation coefficient

Description

This function calculates the correlation coefficient between 'Expression1' and 'Expression2'. The entire recording length is taken into account. The function returns a constant value.

Mcorrel

Mcorrel('Expression1','Expression2','Interval')

Arguments

'Expression1/2'	Signals or expressions for which to calculate the correlation coefficient
'Interval'	Length of the interval over which to calculate the correlation coefficient

Description

This function calculates the correlation coefficient between 'Expression1' and 'Expression2' over floating intervals of the length 'Interval' measured in s, m, Hz or 1/m.

CoVar

CoVar('Expression1','Expression2')

Arguments

'Expression1/2'

Signals or expressions for which to calculate the covariance

Description

This function calculates the covariance between 'Expression1' and 'Expression2'. The entire recording length is taken into account. The function returns a constant value.

MCoVar

MCoVar('Expression1','Expression2','Interval')

Arguments

'Expression1/2'	Signals or expressions for which to calculate the covariance
'Interval'	Length of the interval over which to calculate the covariance

Description

This function calculates the covariance between 'Expression1' and 'Expression2' over floating intervals of the length 'Interval' measured in s, m, Hz or 1/m.
