| Description | As described in connection with MF_SVdecompose and MF_SVsolve, the crucial point in using functions which rely on Singular Value Decomposition is the Singular Value editing step. By default, the SV editing threshold is 4*FLT_EPSILON, 8*DBL_EPSILON, or 16*LDBL_EPSILON. You may change these default values by calling MF_SVDsetEdit. To retrieve the current SV editing threshold, call MF_SVDgetEdit.
As MF_SVDsetEdit is not thread-safe, this function should not be used to set different editing thresholds for different calls to MF_SVsolve etc. Rather than repeatedly changing the default value then, use the "wEdit" variant of MF_SVsolve etc., namely MF_SVsolvewEdit, MF_solveBySVDwEdit and MF_safeSolvewEdit. |
