6.3.3 vsip_dlud_getattr_p - Get LU Decomposition Attributes

typedef struct _vsip_lu_attr_g { 
  vsip_length n; 
} vsip_lu_attr_g; 
 
typedef vsip_lu_attr_g vsip_lu_attr_f; 
typedef vsip_lu_attr_g vsip_clu_attr_f; 
 
void vsip_lud_getattr_f(const vsip_lu_f *lu, vsip_lu_attr_f *attr); 
void vsip_clud_getattr_f(const vsip_clu_f *lu, vsip_lu_cattr_f *attr);

Description

This function retrieves the attributes of an LU decomposition object, this currently includes a single attribute called n for the row and column element count of the square matrix.

Parameters

• const vsip_dlu_p* lu: Pointer to the LU decomposition object.

• vsip_lu_dattr_p* attr: Pointer to a structure where the attributes will be stored.

Example

vsip_lu_f *lu_obj; 
vsip_lu_attr_f attr; 
 
// Assuming lu_obj has been properly initialized 
vsip_lud_getattr_f(lu_obj, &attr); 
 
// attr.n - Number of rows and columns of the square matrix
