Student's *t* probability density function

`y = tpdf(x,nu)`

`y = tpdf(x,nu)`

returns the
probability density function (pdf) of the Student's *t* distribution
at each of the values in `x`

using the corresponding
degrees of freedom in `nu`

. `x`

and `nu`

can
be vectors, matrices, or multidimensional arrays that have the same
size. A scalar input is expanded to a constant array with the same
dimensions as the other inputs.
