Function Documentation

float** get_2D_float( INT16 nr, INT16 nc)

Returns pointers to 2D array (nr,nc) of floats.

Example call: 

  float **test;
  test = get_2D_float( 10,20); assert( test != 0);

test[i][j] can then be accessed as a 2D array i=0..9 and j=0..19

Later test is freed using the associated function: 

  free_2d_float( test, 10);

INT16** get_2D_INT16( INT16 nr, INT16 nc)

Returns pointers to 2D array (nr,nc) of INT16.

Usage is similar to get_2D_float().

WORD** get_2D_WORD( INT16 nr, INT16 nc)

Returns pointers to 2D array (nr,nc) of WORD.

Usage is similar to get_2D_float().

INT32** get_2D_INT32( INT16 nr, INT16 nc)

Returns pointers to 2D array (nr,nc) of INT32.

Usage is similar to get_2D_float().

BYTE** get_2D_BYTE( INT16 nr, INT16 nc)

Returns pointers to 2D array (nr,nc) of BYTE.

Usage is similar to get_2D_float().

BYTE*** get_3D_BYTE( INT16 nr, INT16 nc, INT16 np)

Returns pointers to 3D array (nr,nc,np) of BYTE.

Example call: 

  BYTE ***test;
  test = get_3D_BYTE( 10,20,30); assert( test != 0);

test[i][j][k] can then be accessed as a 3D array i=0..9, j=0..19, k=0..29

Later test is freed using the associated function: 

  free_3D_BYTE( test, 10, 20);

Examples:
Txaper.cpp.

float** get_3D_float( INT16 nr, INT16 nc, INT16 np)

Returns pointers to 3D array (nr,nc,np) of float.

Usage is similar to get_3D_BYTE().

INT16** get_3D_INT16( INT16 nr, INT16 nc, INT16 np)

Returns pointers to 3D array (nr,nc,np) of INT16.

Usage is similar to get_3D_BYTE().

INT32** get_1D_INT32( INT16 n)

Returns pointers to 1D array (n) of INT32.

INT16* get_1D_INT16( INT16 n)

WORD* get_1D_WORD( INT16 n)

BYTE* get_1D_BYTE( INT16 n)

float* get_float( INT16 n)

void free_2D_INT16( INT16 **p, INT16 nr)

void free_2D_WORD( WORD **p, INT16 nr)

void free_2D_float( float **p, INT16 nr)

void free_2D_BYTE( BYTE **p, INT16 nr)

void free_2D_INT32( INT32 **p, INT16 nr)

WORD**** get_4D_WORD( INT16 na, INT16 nb, INT16 nc, INT16 nd)

Returns pointers to 4D array (na, nb, nc, nd) of WORD.

Example call: 

  WORD ****test;
  test = get_4D_WORD( 10,20,30,40); assert( test != 0);

test[i][j][k][l] can then be accessed as a 4D array i=0..9, j=0..19, k=0..29, l=0..39

Later test is freed using the associated function: 

  free_4D_WORD( test, 10, 20, 30);

void free_3D_BYTE( BYTE ***p, INT16 na, INT16 nb)

Examples:
Txaper.cpp.

void free_3D_float( float ***p, INT16 na, INT16 nb)

void free_3D_INT16( INT16 ***p, INT16 na, INT16 nb)
