Function Documentation

Gan_SquMatrix* gan_diagmat_inv_diag_thres (  Gan_SquMatrix *  A,
unsigned  null_space,
double  thres
) 
 

Invert the elements of diagonal matrix.

Returns:
The matrix A, or NULL on failure.
The bottom-right null_space elements of A are set to zero, as well as any other elements below the thres threshold value. All other elements of A are inverted. The elements of diagonal matrix A are assumed to be positive and in decreasing order from the top-left.

Gan_SquMatrix_f* gan_diagmatf_inv_diag_thres (  Gan_SquMatrix_f *  A,
unsigned  null_space,
float  thres
) 
 

Invert the elements of diagonal matrix.

Returns:
The matrix A, or NULL on failure.
The bottom-right null_space elements of A are set to zero, as well as any other elements below the thres threshold value. All other elements of A are inverted. The elements of diagonal matrix A are assumed to be positive and in decreasing order from the top-left.

Gan_Matrix* gan_mat_invert_q (  const Gan_Matrix *  A,
Gan_Matrix *  B
) 
 

Inverts general square matrix.

Parameters:
A Input Matrix
B Output inverse matrix
Returns:
Non-NULL Pointer to the output inverse matrix, or NULL on failure. Inverts general square matrix A into matrix B. This is a nasty operation and should be avoided at all costs.

Gan_Matrix* gan_mat_invert_s (  const Gan_Matrix *  A  ) 
 

Macro: Inverts general square matrix.

Parameters:
A Input Matrix
Returns:
Non-NULL A pointer to the output inverse matrix, or NULL on failure.
Inverts general square matrix A. This is a nasty operation and should be avoided at all costs.

Implemented as a macro call to gan_mat_invert_q().

gan_mat_invert_q().

Gan_Matrix_f* gan_matf_invert_q (  const Gan_Matrix_f *  A,
Gan_Matrix_f *  B
) 
 

Inverts general square matrix.

Parameters:
A Input Matrix
B Output inverse matrix
Returns:
Non-NULL Pointer to the output inverse matrix, or NULL on failure. Inverts general square matrix A into matrix B. This is a nasty operation and should be avoided at all costs.

Gan_Matrix_f* gan_matf_invert_s (  const Gan_Matrix_f *  A  ) 
 

Macro: Inverts general square matrix.

Parameters:
