Matrix Data Structure is defined in SPVM::Matrix::Float and SPVM::Matrix::Double

CLASS METHODS

mat_new

sub mat_new : SPVM::Matrix::Double ($values : double[], $rows_length: int, $columns_length : int)

Create new SPVM::Matrix::Double object.

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. Elements order is assumed as Column-Major order.

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

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

Return Value:

SPVM::Matrix::Double object.

Exception:

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

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

mat_newf

sub mat_newf : SPVM::Matrix::Float ($values : float[], $rows_length: int, $columns_length : int)

Create new SPVM::Matrix::Float object.

Arguments:

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

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

Return Value:

SPVM::Matrix::Float object.

Exception:

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

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