umf_ludel
utility function used with umf_lufact
Syntax
umf_ludel(LU_ptr) or umf_ludel()
Arguments
- LU_ptr
a pointer to a handle of umf lu factors (L,U,p,q,R)
Description
This function must be used in conjunction with umf_lufact and umf_lusolve. It clears the internal memory space used to store the LU factors (got with umf_lufact). Use without argument it frees the memory for all the current scilab umfpack LU factors.
Examples
see the example section of umf_lufact
