void* xmalloc ( size_t size )

Allocates memory with check and (eventually) error reporting.

Here is the caller graph for this function:

void* xrealloc	(	void *	ptr,
		size_t	size
	)

Reallocates memory.

Definition at line 24 of file misc.c.

Variable Documentation

double* dr

Definition at line 24 of file cstream.c.

double * dz

Definition at line 24 of file cstream.c.

double dtheta

The grid sizes

dr[i] and dz[i] represent the grid size at level i. Note that i can go from -extra_pois_levels...max_levels.

Definition at line 24 of file cstream.c.

double* w2k

Definition at line 29 of file cstream.c.

double * wk

See cstream.c

w2k[k] = 2 / dtheta^2 (1 - cos(k dtheta)). This numbers appear due to the finite-differences derivatives of a Fourier transform. If we would make a continuous fourier transform, they will approach k^2.

Definition at line 29 of file cstream.c.

char* invok_name

Name of this program.

Definition at line 36 of file cstream.c.

const double twopi

$2 \times \pi$ .
