Types and Values

BMatrixSize

typedef struct {
  unsigned int rows;
  unsigned int columns;
} BMatrixSize;

Holds the size of a matrix.

Members

unsigned int `rows`;	rows number, includes missing values.
unsigned int `columns`;	columns number, includes missing values.

struct BMatrixClass

struct BMatrixClass {
  BDataClass base;

  BMatrixSize(*load_size) (BMatrix * vec);
