Detailed Description

template<typename, size_t, bool>
class blaze::StaticVector< typename, size_t, bool >

Efficient implementation of a fixed-sized vector.

The StaticVector class template is the representation of a fixed-size vector with statically allocated elements of arbitrary type. The type of the elements, the number of elements and the transpose flag of the vector can be specified via the three template parameters:

template< typename Type, size_t N, bool TF >

These contiguously stored elements can be direclty accessed with the subscript operator. The numbering of the vector elements is

\[\left(\begin{array}{*{4}{c}} 0 & 1 & \cdots & N-1 \\ \end{array}\right)\]

The use of StaticVector is very natural and intuitive. All operations (addition, subtraction, multiplication, scaling, ...) can be performed on all possible combinations of dense and sparse vectors with fitting element types. The following example gives an impression of the use of a 2-dimensional StaticVector:

StaticVector<double,2UL> a, // Default initialized 2D vectors
a[0] = 1.0; // Initialization of the first element
a[1] = 2.0; // Initialization of the second element
StaticVector<double,2UL> b( 3.0, 2.0 ); // Directly initialized 2D vector
CompressedVector<float> c( 4.0F ); // Empty single precision vector
StaticVector<double,2UL> d; // Default constructed static vector
StaticMatrix<double,2UL,2UL> A; // Default constructed static row-major matrix
d = a + b; // Vector addition between vectors of equal element type
d = a - c; // Vector subtraction between vector of different element type
d = a * b; // Component-wise vector multiplication
a *= 2.0; // In-place scaling of vector
d = a * 2.0; // Scaling of vector a
d = 2.0 * a; // Scaling of vector a
d += a - b; // Addition assignment
d -= a + c; // Subtraction assignment
d *= a * b; // Multiplication assignment
double scalar = trans( a ) * b; // Scalar/dot/inner product between two vectors
A = a * trans( b ); // Outer product between two vectors

template<typename , size_t , bool >
anonymous enum

Compilation flag for intrinsic optimization.

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