NAME

SPVM::Matrix::QuatLong - quat long Matrix

SYNOPSYS

my $values = new SPVM::Quat_4l[10];
my $row = 2;
my $col = 3;
my $matrix = SPVM::Matrix::QuatLong->new($values, $row, $col);

Accessors

my $values = $matrix->values;
my $row = $matrix->row;
my $col = $matrix->col;

DESCRIPTION

SPVM::Matrix::QuatLong is quat long Matrix.

METHODS

new : SPVM::Matrix::QuatLong ($values : ${element_type}[], $row : int, $col : int)

my $values = new SPVM::Quat_4l[10];
my $row = 2;
my $col = 3;
my $matrix = SPVM::Matrix::QuatLong->new($values, $row, $col);

Arguments:

1. Values. this value is set to values field. Note that the reference is set to values field not creating new array which elements is copied from argument array.

2. Row. This value is set to row field.

3. Column. This value is set to col field.

Return Value:

Matrix object.

Exception:

1. If Values is not defined, a exception occurs.

2. If Values length is different from Row * Column, a exception occurs.

values : ${element_type}[] ()

my $values = $matrix->values;

Get values field. Note that get the reference of values field not creating new array which elements is copied from values field.

row : int ()

my $row = $matrix->row;

Get row field.

col : int ()

my $col = $matrix->col;

Get col field.

to_string : string ()

my $string = $matrix->to_string;

Convert Matrix Content to String. Each column is joined 1 space and Each row is end with \n

1 3 5
2 4 6

Matrix Features

Values is always defined

values field is alway defined after new matrix object.

Array length of Values is always Row length * Column length

The array length of values is always row field * col field.

Column-major

Matrix is Column-major.

# Matrix
# $x11 $x12 $x13
# $x21 $x22 $x23
my $values = [$x11, $x21, $x12, $x22, $x13, $x23];
my $row = 2;
my $col = 3;
my $matrix = SPVM::Matrix::QuatLong->new($values, $row, $col);

Imutable Things

The following fields is imutable.

1. values field

2. row field

3. col field

Mutable Things

The following thing is mutable.

1. Each value of values field.

# Can set each value of C<values> field.
$matrix->values->[0] = $x11;
