StdDev
StdDev('Expression')
Description
This function returns the standard deviation of 'Expression'.
The standard deviation is calculated by the following formula:
StdDevInTime
StdDevInTime('Expression','Interval')
Arguments
|
'Expression' |
Signal or expression for which to form the standard deviation |
|
'Interval' |
Length of the interval over which to calculate the standard deviation |
Description
This function returns the standard deviation of 'Expression' over each time interval of the length 'Interval'.
Note |
|
|---|---|
 |
The result of the StdDevInTime function is always specified for the previous interval. |
StdDevValid
StdDevValid('Expression','Valid')
Arguments
|
'Expression' |
Signal or expression for which to form the standard deviation |
|
'Valid' |
Control signal |
Description
This function returns the standard deviation of 'Expression' for the interval (time or length) where a related control signal is TRUE.
MStdDev
MStdDev('Expression','Interval')
Arguments
|
'Expression' |
Signal or expression for which to form the standard deviation |
|
'Interval' |
Length of the interval over which to calculate the standard deviation |
Description
This function returns the floating standard deviation of 'Expression' over each time interval of the length 'Interval'. You can use this function for time based signals ('Interval' in seconds) as well as for length based signals ('Interval' in meters).
