Student's *t* probability density function

`tpdf`

is a function specific to the Student's*t*distribution. Statistics and Machine Learning Toolbox™ also offers the generic function`pdf`

, which supports various probability distributions. To use`pdf`

, specify the probability distribution name and its parameters. Note that the distribution-specific function`tpdf`

is faster than the generic function`pdf`

.Use the

**Probability Distribution Function**app to create an interactive plot of the cumulative distribution function (cdf) or probability density function (pdf) for a probability distribution.
