6.3.1 vsip_dlud_create_p - Create LU Decomposition Object

vsip_lu_f* vsip_lud_create_f(vsip_length n); 
vsip_clu_f* vsip_clud_create_f(vsip_length n);

Description

This function creates an LU decomposition object for factoring an matrix into the product of a lower triangular matrix and an upper triangular matrix . The object can be reused for multiple decompositions of matrices with the same dimensions.

Parameters

• vsip_length n: Number of rows and columns in the matrix to be decomposed.

Return Value

• On success, a pointer to the newly created LU decomposition object is returned.

• On error, NULL is returned.

Example

vsip_lu_f *lu_obj; 
vsip_length n = 100; 
 
// Create LU decomposition object 
lu_obj = vsip_lud_create_f(n); 
 
if (lu_obj == NULL) { 
    // Handle error 
}
