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