Detailed Description

template<typename Type, size_t M, size_t N, bool SO = defaultStorageOrder>
class blaze::StaticMatrix< Type, M, N, SO >

Efficient implementation of a fixed-sized matrix.

The StaticMatrix class template is the representation of a fixed-size matrix with statically allocated elements of arbitrary type. The type of the elements, the number of rows and columns and the storage order of the matrix can be specified via the four template parameters:

template< typename Type, size_t M, size_t N, bool SO >

Depending on the storage order, the matrix elements are either stored in a row-wise fashion or in a column-wise fashion. Given the 2x3 matrix

\[\left(\begin{array}{*{3}{c}} 1 & 2 & 3 \\ 4 & 5 & 6 \\ \end{array}\right)\]


in case of row-major order the elements are stored in the order

\[\left(\begin{array}{*{6}{c}} 1 & 2 & 3 & 4 & 5 & 6. \\ \end{array}\right)\]

In case of column-major order the elements are stored in the order

\[\left(\begin{array}{*{6}{c}} 1 & 4 & 2 & 5 & 3 & 6. \\ \end{array}\right)\]

The use of StaticMatrix is very natural and intuitive. All operations (addition, subtraction, multiplication, scaling, ...) can be performed on all possible combinations of row-major and column-major dense and sparse matrices with fitting element types. The following example gives an impression of the use of StaticMatrix:

StaticMatrix<double,2UL,3UL,rowMajor> A; // Default constructed, non-initialized, row-major 2x3 matrix
A(0,0) = 1.0; A(0,1) = 2.0; A(0,2) = 3.0; // Initialization of the first row
A(1,0) = 4.0; A(1,1) = 5.0; A(1,2) = 6.0; // Initialization of the second row
DynamicMatrix<float,2UL,3UL,columnMajor> B; // Default constructed column-major single precision 2x3 matrix
B(0,0) = 1.0; B(0,1) = 3.0; B(0,2) = 5.0; // Initialization of the first row
B(1,0) = 2.0; B(1,1) = 4.0; B(1,2) = 6.0; // Initialization of the second row
CompressedMatrix<float> C( 2, 3 ); // Empty row-major sparse single precision matrix
StaticMatrix<float,3UL,2UL> D( 4.0F ); // Directly, homogeneously initialized single precision 3x2 matrix
StaticMatrix<double,2UL,3UL,rowMajor> E( A ); // Creation of a new row-major matrix as a copy of A
StaticMatrix<double,2UL,2UL,columnMajor> F; // Creation of a default column-major matrix
E = A + B; // Matrix addition and assignment to a row-major matrix
F = A - C; // Matrix subtraction and assignment to a column-major matrix
F = A * D; // Matrix multiplication between two matrices of different element types
A *= 2.0; // In-place scaling of matrix A
E = 2.0 * B; // Scaling of matrix B
E = B * 2.0; // Scaling of matrix B
E += A - B; // Addition assignment
E -= A + C; // Subtraction assignment
F *= A * D; // Multiplication assignment

Member Enumeration Documentation

◆ anonymous enum

template<typename Type, size_t M, size_t N, bool SO = defaultStorageOrder>
anonymous enum : bool

Compilation flag for SIMD optimization.

The simdEnabled compilation flag indicates whether expressions the matrix is involved in can be optimized via SIMD operations. In case the element type of the matrix is a vectorizable data type, the simdEnabled compilation flag is set to true, otherwise it is set to false.

◆ anonymous enum

template<typename Type, size_t M, size_t N, bool SO = defaultStorageOrder>
anonymous enum : bool

Compilation flag for SMP assignments.

The smpAssignable compilation flag indicates whether the matrix can be used in SMP (shared memory parallel) assignments (both on the left-hand and right-hand side of the assignment).

Constructor & Destructor Documentation

◆ StaticMatrix() [1/8]

template<typename Type , size_t M, size_t N, bool SO>
blaze::StaticMatrix< Type, M, N, SO >::StaticMatrix ( )
inlineexplicit

The default constructor for StaticMatrix.

All matrix elements are initialized to the default value (i.e. 0 for integral data types).

◆ StaticMatrix() [2/8]

template<typename Type , size_t M, size_t N, bool SO>
blaze::StaticMatrix< Type, M, N, SO >::StaticMatrix ( const Type &  init)
inlineexplicit

Constructor for a homogenous initialization of all elements.

Parameters
initInitial value for all matrix elements.

◆ StaticMatrix() [3/8]

template<typename Type , size_t M, size_t N, bool SO>
blaze::StaticMatrix< Type, M, N, SO >::StaticMatrix ( initializer_list< initializer_list< Type > >  list)
inlineexplicit

List initialization of all matrix elements.

Parameters
listThe initializer list.
Exceptions
std::invalid_argumentInvalid setup of static matrix.

This constructor provides the option to explicitly initialize the elements of the matrix by means of an initializer list:

{ 4, 5 },
{ 7, 8, 9 } };

The matrix elements are initialized by the values of the given initializer list. Missing values are initialized as default (as e.g. the value 6 in the example). Note that in case the size of the top-level initializer list exceeds the number of rows or the size of any nested list exceeds the number of columns, a std::invalid_argument exception is thrown.

◆ StaticMatrix() [4/8]

template<typename Type , size_t M, size_t N, bool SO>
template<typename Other >
blaze::StaticMatrix< Type, M, N, SO >::StaticMatrix ( size_t  m,
size_t  n,
const Other *  array 
)
inlineexplicit

Array initialization of all matrix elements.

Parameters
mThe number of rows of the matrix.
nThe number of columns of the matrix.
arrayDynamic array for the initialization.

This constructor offers the option to directly initialize the elements of the matrix with a dynamic array:

int* array = new int[6];
// ... Initialization of the dynamic array
delete[] array;

The matrix is initialized with the values from the given array. Missing values are initialized with default values. In case the specified number of rows and/or columns exceeds the maximum number of rows/column of the static matrix (i.e. m is larger than M or n is larger than N), a std::invalid_argument exception is thrown.
Note that it is expected that the given array has at least m by n elements. Providing an array with less elements results in undefined behavior!

◆ StaticMatrix() [5/8]

template<typename Type , size_t M, size_t N, bool SO>
template<typename Other , size_t Rows, size_t Cols>
blaze::StaticMatrix< Type, M, N, SO >::StaticMatrix ( const Other(&)  array[Rows][Cols])
inlineexplicit

Array initialization of all matrix elements.

Parameters
array$ M \times N $ dimensional array for the initialization.

This constructor offers the option to directly initialize the elements of the matrix with a static array:

const int init[3][3] = { { 1, 2, 3 },
{ 4, 5 },
{ 7, 8, 9 } };

The matrix is initialized with the values from the given array. Missing values are initialized with default values (as e.g. the value 6 in the example).

◆ StaticMatrix() [6/8]

template<typename Type , size_t M, size_t N, bool SO>
blaze::StaticMatrix< Type, M, N, SO >::StaticMatrix ( const StaticMatrix< Type, M, N, SO > &  m)
inline

The copy constructor for StaticMatrix.

Parameters
mMatrix to be copied.

The copy constructor is explicitly defined in order to enable/facilitate NRV optimization.

◆ StaticMatrix() [7/8]

template<typename Type , size_t M, size_t N, bool SO>
template<typename Other , bool SO2>
blaze::StaticMatrix< Type, M, N, SO >::StaticMatrix ( const StaticMatrix< Other, M, N, SO2 > &  m)
inline

Conversion constructor from different StaticMatrix instances.

Parameters
mMatrix to be copied.

◆ StaticMatrix() [8/8]

template<typename Type , size_t M, size_t N, bool SO>
template<typename MT , bool SO2>
blaze::StaticMatrix< Type, M, N, SO >::StaticMatrix ( const Matrix< MT, SO2 > &  m)
inline

Conversion constructor from different matrices.

Parameters
mMatrix to be copied.
Exceptions
std::invalid_argumentInvalid setup of static matrix.

This constructor initializes the static matrix from the given matrix. In case the size of the given matrix does not match the size of the static matrix (i.e. the number of rows is not M or the number of columns is not N), a std::invalid_argument exception is thrown.
