unsigned ArrayBase::dim ( unsigned  i  )  const [inline, inherited]

Returns the size of the i-th dimension of the array.

Parameters:
i the dimension of which the size will be returned.
Returns:
the size of dimension i.
Exceptions:
SharkException the type of the exception will be "range check error" and denotes, that the value of i exceeds the number of dimensions of the array.
