Parameters
x:
real vector.
Fs:
specifies the sample rate, Fs, as a positive scalar, where the first sample instant corresponds to a time of zero.
t:
defiene instant sample time t as vector with same length of x, or specifies the sample rate, t, as a positive scalar.
PercentReferenceLevels:
specify the percentreferenceleves as a percentage, default value of N is [10 90].
Tolerance:
define the tolerance value as real scaler value, where default value of M is 2.0.
StateLevels:
define the lower and upper state levels as two element real vector.
fig:
specify the logical input value to display figure as one of 'on' or 'off', where the default input in 'off'.
f:
return fall time of negative-going bilevel waveform transitions X.
lowercrossvalue:
return the lowerc cross value.
uppercrossvalue:
return the upper cross value.
lowerreference:
return lower reference value corrosponding to lower percent reference value.
upperreference:
return upper reference value corrosponding to upper percent reference value.
