umf_ludel

Arguments

LU_ptr

a pointer to an 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
