NAME

SPVM::AI::Util - AI Utilities for array operations, matrix operations, activate function, and cost function etc.

VERSION

Version 0.01

SYNOPSIS

Quick summary of what the module does.

Perhaps a little code snippet.

    use SPVM::AI::Util;

    my $mat1 = SPVM::AI::Util->mat_newf([1.2f, 1.3, 1.4], 3, 2);
    my $mat2 = SPVM::AI::Util->mat_newf([1.5f, 1.1, 1.2], 3, 2);
    
    my $mat_add = SPVM::AI::Util->mat_addf($mat1, $mat2);

DESCRIPTION

SPVM::AI::Util is AI Utilities for array operations, matrix operations, activate function, and cost function etc.

This is SPVM module. You can write programing logic using SPVM Language or binding C/C++/cuda language.

STATIC METHODS

mat_newf

  sub mat_newf : SPVM::AI::Util::FloatMatrix ($values : float[], $rows_length: int, $columns_length : int)

Create new SPVM::AI::Util::FloatMatrix 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::AI::Util::FloatMatrix object.

Exception:

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

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

mat_new_zerof

  sub mat_new_zerof : SPVM::AI::Util::FloatMatrix ($rows_length: int, $columns_length : int)

Create new SPVM::AI::Util::FloatMatrix object with zero value.

mat_new_identf

  sub mat_new_identf : SPVM::AI::Util::FloatMatrix ($dim : int)

Create new ident <SPVM::AI::Util::FloatMatrix> by specifing the dimention.

mat_transposef

  sub mat_transposef : SPVM::AI::Util::FloatMatrix ($mat : SPVM::AI::Util::FloatMatrix)

Transpose float matrix and return new SPVM::AI::Util::FloatMatrix object.

mat_addf

  sub mat_addf : SPVM::AI::Util::FloatMatrix ($mat1 : SPVM::AI::Util::FloatMatrix, $mat2 : SPVM::AI::Util::FloatMatrix)

Add two float Matrix and return new SPVM::AI::Util::FloatMatrix object.

mat_subf

  sub mat_subf : SPVM::AI::Util::FloatMatrix ($mat1 : SPVM::AI::Util::FloatMatrix, $mat2 : SPVM::AI::Util::FloatMatrix)

Subtract two float Matrix and return new SPVM::AI::Util::FloatMatrix object.

mat_scamulf

  sub mat_scamulf : SPVM::AI::Util::FloatMatrix ($scalar : float, $mat1 : SPVM::AI::Util::FloatMatrix)

Scalar multiply float matrix and return new SPVM::AI::Util::FloatMatrix object.

mat_mulf

  sub mat_mulf : SPVM::AI::Util::FloatMatrix ($mat1 : SPVM::AI::Util::FloatMatrix, $mat2 : SPVM::AI::Util::FloatMatrix)

Multiply two float Matrix and return new SPVM::AI::Util::FloatMatrix object.

mat_strf

  sub mat_strf : string ($mat : SPVM::AI::Util::FloatMatrix)

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