Matrices in Home View
Page 467 of the User Guide: Entering matrices directly (shift5):
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 shift5 to vectors only. Both the emulator and the device seem to respond this way. Dale

RE: Matrices in Home View
Try keying Shift5 twice. Keying Shift5 the second time will make the vector a matrix.
Pressing Shift5 Once: Vector editing mode Pressing Shift5 Twice: Matrix editing mode Subsequent pressing of Shift5: toggle between vector and matrix Hope this helps.

RE: Matrices in Home View
Yes, indeed a second shift5 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.

RE: Matrices in Home View
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.

RE: Matrices in Home View
I noticed these changes. A small change that is a great improvement.
Much better than the old way!
