Update:

Keyboard stopped working in Matlab again.  

As it occurred, I was typing a statement in the terminal window and used tab to autocomplete, which then made the length of the statement  greater than the display width of the terminal window. It was at that point keyboard input ceased. Have not replicated this yet though. 

Time of onset: 1.08pm. 
Checked Ubuntu system logs: no errors for 1.08 pm 
Disabled Compiz advanced graphics effects - no change
Copied and pasted text into terminal using mouse, then typed - no change
Cycled to other app windows using Alt-Tab and back to Matlab - no change
Time of Matlab restart: 2.17 pm
