Matrix identification bug (PR#1361)
...abnormal result 9.4s from
PIII-M 1.2GHz (cannot be three times faster). After using native fortran lapack
(call to dpotrf and dpotri returns 9s for PIII Xeon), I realized that R may
treat the matrix as a general matrix rather than symmetric except the abnormal
case. To confirm this, I modified the R_LapackPP.cc in Matrix package and it
turned out that
is.MMatrix() failed to return true.
Hence
if (checkClass(classes, "Hermitian"))
return new LaSymmMatDouble(x);
is not executed in static LaMatDouble* asLaMatrix(SEXP x). Instead
if (isMatrix(x)) {
return...
