Product of elements along dimension dim.
If dim is omitted, it defaults to the first non-singleton dimension.
The optional "type"
input determines the class of the variable
used for calculations. If the argument "native"
is given, then
the operation is performed in the same type as the original argument, rather
than the default double type.
For example:
prod ([true, true]) ⇒ 1 prod ([true, true], "native") ⇒ true
On the contrary, if "double"
is given, the operation is performed
in double precision even for single precision inputs.
