taucs_chdel

utility function used with taucs_chfact

Calling Sequence

taucs_chdel(C_ptr) or taucs_chdel()

Arguments

:C_ptr a pointer to a Cholesky factorization :

Description

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.

Examples

see the example section of taucs_chfact
