t = truncate(pd,lower,upper)
returns a probability distribution t, which is the probability
distribution pd truncated to the specified interval with lower
limit, lower, and upper limit,
upper.

t — Truncated distribution probability distribution object

Truncated distribution, returned as a probability distribution object. The
probability distribution function (pdf) of t is 0
outside the truncation interval. Inside the truncation interval, the pdf of
t is equal to the pdf of pd,
but divided by the probability assigned to that interval by
pd.

The object properties of t are
the same as those of pd with these exceptions:

The Truncation property of
t stores the truncation
interval.

The IsTruncated property of
t is 1.

The InputData property of
t is empty. For a fitted distribution
object, the InputData property stores the
data used for distribution fitting. The truncated distribution
object does not store the input data.

Usage notes and limitations:

The input argument pd can be a fitted probability
distribution object for beta, exponential, extreme value, lognormal, normal,
and Weibull distributions. Create pd by fitting a
probability distribution to sample data from the fitdist function. For an
example, see Code Generation for Probability Distribution Objects.

A truncated probability distribution object cannot be an input argument of
an entry-point function. To evaluate a truncated distribution using object
functions such as cdf, pdf,
mean, and so on, call truncate
and one or more of these object functions within a single entry-point
function.
