static double** coco_allocate_blockmatrix	(	const size_t	n,
		const size_t *	block_sizes,
		const size_t	nb_blocks
	)

static

Allocate a ${n} by ${m} block matrix of nb_blocks block sizes block_sizes structured as an array of pointers to double arrays. each row contains only the block_sizes[i] possibly non-zero elements.

static void coco_compute_blockrotation	(	double **	B,
		long	seed,
		size_t	n,
		size_t *	block_sizes,
		size_t	nb_blocks
	)

static

Compute a ${DIM}x${DIM} block-diagonal matrix based on ${seed} and block_sizes and stores it in ${B}. B is a 2D vector with DIM lines and each line has blocksize(line) elements (the zeros are not stored)

static double** coco_copy_block_matrix	(	const double const	B,
		const size_t	dimension,
		const size_t *	block_sizes,
		const size_t	nb_blocks
	)

static

makes a copy of a block_matrix

static void coco_free_block_matrix	(	double **	matrix,
		const size_t	n
	)

static

frees a block diagonal matrix (same as a matrix but in case of change, easier to update separately from free_matrix)

static size_t* coco_get_block_sizes	(	size_t *	nb_blocks,
		size_t	dimension,
		const char *	suite_name
	)

static

returns the list of block_sizes and sets nb_blocks to its correct value

static size_t coco_rotation_matrix_block_size ( size_t const dimension )

static

Returns block size for block rotation matrices.
