elementwise binary operators: Binary Operators
Description
This page documents the operators "*", "+", "-", "/", "^", "%%",
"=", "<"< code="">, ">", ">=", "<="< code="">, "!=", "&" and "|".
These are all element-wise binary operations that can be performed on a gmatrix or gvector object.
Operators work in much that same way as in R base. The command e1 %lgspadd% e2 yields the vector
log(exp(e1)+exp(e2)) calculated in a numericaly stable way.
If one object is shorter than the other, items in the shorter object are recycled as in R base. All operations
return a GPU object (i.e. a gmatrix or gvector).

Warning
The operator %% is known to be numericaly instable compared to the R version.
