Subject: MMULT dimensions
Hi, MMULT has | Portable Constraints: Both matrices must have the same dimensions. and | TODO: We should probably instead REQUIRE support for matrix | multiplication when they don't have the same dimentions. How was that meant? Matrix multiplication is defined for columns()==rows(), the two matrices don't need to have the same dimensions. So the portable constraint is moot. Eike -- Automatic string conversions considered dangerous. They are the GOTO statements of spreadsheets. --Robert Weir on the OpenDocument formula subcommittee's list.
