Matrices in Home View - DrD - 05-30-2014 11:15 AM
Page 467 of the User Guide: Entering matrices directly (shift-5): I can enter vectors, but I am not able to enter m x n matrices. The command line does not respond to the down arrow to create additional rows. This behavior limits shift-5 to vectors only. Both the emulator and the device seem to respond this way. -Dale- RE: Matrices in Home View - Eddie W. Shore - 05-30-2014 12:12 PM
Try keying Shift-5 twice. Keying Shift-5 the second time will make the vector a matrix. Pressing Shift-5 Once: Vector editing mode Pressing Shift-5 Twice: Matrix editing mode Subsequent pressing of Shift-5: toggle between vector and matrix Hope this helps.

Yes, indeed a second shift-5 does the job! This may be new behavior, a down arrow entry used to move to additional rows, if I remember correctly. Thanks for that. -Dale- RE: Matrices in Home View - Tim Wessman - 05-30-2014 02:30 PM
The vector/matrix input did change. Before, a single line, single bracket item showed 2 rows with the +- symbols at each place. However, this made it extreemly difficult to see whether something was a vector or a matrix at a glance. There are two ways to make a vector into a matrix - either press the [ ] again (you can toggle back and forth between them) or else position the cursor on the +- at the end and press the + key.

I noticed these changes. A small change that is a great improvement. Much better than the old way! |
