MatrixInfo

Some reflective information about multidimensional arrays

Handles dynamic arrays, static arrays, and pointers to static arrays.

Members

Aliases

MatrixElementType alias MatrixElementType = _dim.elt: Matrix element type of T E.g. immutable(double) for T=immutable(double[4][4])
RectArrayType alias RectArrayType = _rect_type!(unqual, 0): unqualified highest dimension subtype of T forming RectArray
dim_list alias dim_list = _dim.list: tuple of dimensions of T. dim_list[0] will be the dimension furthest from the MatrixElementType i.e. for double[1][2][3], dim_list == (3, 2, 1). Lists -1 as dimension of dynamic arrays.
unqual alias unqual = _dim.unqual*: T, with all nonmutable qualifiers stripped away.

Functions

build_shape Py_ssize_t[] build_shape(T t): Build shape from t. Assumes all arrays in a dimension are initialized and of uniform length.
check bool check(Py_ssize_t[] shape): Ensures that T can store a matrix of _shape shape.
matrixIter string matrixIter(string arr_name, string shape_name, string index_name, size_t ndim, string pre_code, string post_code): Generate a mixin string of nested for loops that iterate over the first ndim dimensions of an array of type T (or, preferrably MatrixInfo!T.unqual).

Manifest constants

ndim enum ndim;: number of dimensions of this matrix

Variables

dimstring enum string dimstring;: Pretty string of dimension list for T
isRectArray enum bool isRectArray;: T is a RectArray if: * it is any multidimensional static array (or a pointer to) * it is a 1 dimensional dynamic array
rectArrayAt enum size_t rectArrayAt;: Highest dimension where it and all subsequent dimensions form a RectArray.
