SMOOTH(input,delay time) exponential SMOOTH
SMOOTHI(input,delay time,initial value) exponential SMOOTH with Initial

Returns a exponential smooth of the input. Equivalent to the equations:

SMOOTH=INTEG((input-SMOOTH)/delay time,input)

SMOOTHI=INTEG((input-SMOOTHI)/delay time,initial value)

See also: DELAY1, DELAY3, SMOOTH3,DELAYP

Units: SMOOTH(units,time) --> units

 SMOOTHI(units,time,units) --> units

The input units match the output units. The units of delay time must match those of TIME  STEP. For SMOOTHI units for the initial value must match those of the input.

Example

S = STEP(10,40)

SS = SMOOTH(S,20)

SSI = SMOOTHI(S,20,5)
