Entry line Matrix editing
Is it (is) or is it (is not) able to insert a row in a matrix on the ENTRY LINE BEFORE the first row?
The virtual calc Help|User Guide suggests I can make any size matrix, but it offered no suggestion on how to increase a matrix before element (1,1). Example: Entry line contains --> [[1,2,3],[9,8,7]] append this --> [0,0,0] making it thus --> [[0,0,0],[1,2,3],[9,8,7]] +/- doesn't seem to do 'before row' editing. -Dale- |

Yes: use the [×] key instead of [+] when the cursor is on the ± symbol at the top of the last column (or at the beginning of the bottom row). [+] inserts row/column AFTER current one. [×] inserts row/column BEFORE current one. [-] deletes current row/column. <0|ɸ|0> -Joe- |

O I C,
One can use the [X] key while using the (virtual or Prime) keypads; or use the '*' key, if using the computer keyboard, to insert a row before a row, thanks, that's good to know! I must've tried a thousand things, all of which failed miserably. I've re-read page 467 of the User Guide too many times, and that tidbit sure escapes my eyes. (Thanks would go to the author / proof-readers if they would actually put it there.) You have been most helpful, kind sir! I should be forced to poke [X] into a matrix 100 times on the black-screen to help me remember! -Dale- |
