Name
SPVM::R::OP::Short - N-Dimensional Array Operations for R::NDArray::Short
Description
R::OP::Short class in SPVM has methods for n-dimensional array operations for R::NDArray::Short.
Usage
use R::OP::Short as SOP;
my $ndarray_scalar = SOP->c((short)1);
my $ndarray_vector = SOP->c([(short)1, 2, 3]);
my $ndarray = SOP->c([(short)1, 2, 3, 4, 5, 6], [3, 2]);
my $ndarray2 = SOP->c($ndarray);Class Methods
c
static method c : R::NDArray::Short ($data : object of Short|short[]|R::NDArray::Short, $dim : int[] = undef);
Creates a new R::NDArray::Short object given the data $data and the dimensions $dim.
Implemetation:
If $data is defined and the type of $data is Short, $data is set to [(short)$data-(Short)]>.
If $data is defined and the type of $data is R::NDArray::Short, $dim is set to $data->(R::NDArray::Short)->dim unless $dim is defined and $data is set to $data->(R::NDArray::Short)->data.
And this method calls R::NDArray::Short#new method given $dim and $data.
Exceptions:
The type of the data $data must be Short, short[], or R::NDArray::Short if defined. Othrewise, an exception is thrown.
rep
static method rep : R::NDArray::Short ($x_ndarray : R::NDArray::Short, $times : int);
Same as R::OP#rep method, but the return type is different.
rep_length
static method rep_length : R::NDArray::Short ($x_ndarray : R::NDArray::Short, $length : int);
Same as R::OP#rep_length method, but the return type is different.
seq
static method seq : R::NDArray::Short ($begin : short, $end : short, $by : short = 1);
Creates a R::NDArray::Short object from $bigin to $end at intervals of $by.
Exceptions:
$by must not be 0. Otherwise, an exception is thrown.
If $by is greater than 0 and $end is not greater than or equal to $begin, an exception is thrown.
If $by is less than 0 and $end Is not greater than or equal to $begin, an exception is thrown.
