Global Constants

constexpr layout COLUMN_MAJOR: Specifies that elements should be laid out in column-major order.

constexpr layout ROW_MAJOR: Specifies that elements should be laid out in row-major order.

constexpr layout DEFAULT_LAYOUT

The default layout for tensors (either row- or column-major).

This value is controlled by the macro MARRAY_DEFAULT_LAYOUT.

constexpr index_base BASE_ZERO: Specifies that indices should start at 0.

constexpr index_base BASE_ONE: Specifies that indices should start at 1.

constexpr c_cxx_t C

Specifies row-major layout and base-0 indices.

Convertible to either layout or index_base. Same as CXX.

constexpr c_cxx_t CXX

Specifies row-major layout and base-0 indices.

Convertible to either layout or index_base. Same as C.

constexpr fortran_t FORTRAN

Specifies column-major layout and base-1 indices.

Convertible to either layout or index_base. Same as MATLAB.

constexpr fortran_t MATLAB

Specifies column-major layout and base-1 indices.

Convertible to either layout or index_base. Same as FORTRAN.

constexpr index_base DEFAULT_BASE

The default base for indices (either 0 or 1).

This value is controlled by the macro MARRAY_DEFAULT_BASE.

constexpr all_t all: Token used to select all indices along a dimension.

constexpr bcast_t bcast

Token used to create a new dimension along which the tensor will be replicated.

This can be used to broadcast data into a destination tensor of larger dimensionality, e.g.:

marray<3> A{3,5,8};
marray<4> B{3,6,5,8};
B = A[all][bcast][all][all];
//now B[i][j][k][l] == A[i][k][l] for all j

constexpr uninitialized_t uninitialized

A token which indicates not to initialize allocated memory.

This special value is used to construct an array which does not default- or value-initialize its elements (useful for avoiding redundant memory operations for scalar types).

constexpr int DYNAMIC: Special value which indicates that the number of dimensions is not known at compile time.
