[eigen] [eigen3] .cwise() vs .array() and static assertion

[ Thread Index | Date Index | More lists.tuxfamily.org/eigen Archives ]


Hi,

I am starting using eigen3
I got this message

THE_EVAL_EVALTO_FUNCTION_SHOULD_NEVER_BE_CALLED_FOR_DENSE_OBJECTS

triggered by this code:

tmp -= (0.5 * ii)*scalings().row( ii-1 ).array()*bs[ii].row( jj ).array();

any idea what this means ?

The code was compiling before with cwise()

tmp -= (0.5 * ii)*scalings().row( ii-1 ).cwise()*bs[ii].row( jj );

Best regards
C.
