Справка Scilab >> UMFPACK Interface (sparse) > taucs_chdel


utility function used with taucs_chfact


taucs_chdel(C_ptr) or taucs_chdel()



a pointer to a Cholesky factorization


This function is used in conjunction with taucs_chfact and taucs_chsolve. It clears the internal memory space used to store the Cholesky factorization (got with taucs_chfact). Use without argument it frees the memory for all the current scilab (taucs) Cholesky factorizations.


see the example section of taucs_chfact
