84772 1095 d 6 h maechler /branches/R-OBJSXP/ 'Create R-OBJSXP branch - new OBJSXP type "==" S4SXP = "object" in R'  
72294 3434 d 21 h kalibera /trunk/ Fix complex number multiplication in matrix product to match
scalar/element-wise complex number multplication in complex.c (the
difference was in treatment of Inf/NaN in inputs).		  
72142 3456 d 1 h kalibera /trunk/ Allow selection of matprod implementations (default, internal, blas and
experimental default.simd). Check inputs for NaN/Inf also for symmetrical
case. The default is to bypass BLAS when input may have NaN/Inf.		  
72083 3461 d 22 h kalibera /trunk/ Bypass ZGEMM for inputs with NaN/Inf. Fix backup C code for complex matprod
so that it does not turn NaN into NA unnecessarily. Fix complex
(t)crossprod to work when Fortan and C disagree on complex numbers layout
(previously only cmatprod supported this).		  
72036 3468 d 2 h kalibera /trunk/ Use DGEMV instead of DGEMM for matrix-vector and vector-matrix
multiplication (performance optimization).		  
53588 5734 d 1 h ripley /trunk/ separate out the BLAS regression tests
