Details:

Try the following steps:


a = num2cell (rand (3));
a{2, 3} = rand (2);
openvar ('a')


Now, in the V.E., double-click on the 2,3 cell that indicates "[2x2 double]"
and the window a{2,3} appears.  Now go back to the command window and type


a{2,3} = 10


(Leave off the semicolon so the contents is printed.)  Look back at the V.E. 
Both the "a" and "a{2,3}" will have been updated properly; they both indicate
"10".  Now, go to the "a{2,3}" window and change the value of the 1,1 cell
from 10 to 500.  Look over in the "a" tab window and the cell at 2,3 still
indicates "10".  Go to the command line and look at "a":


>> a
a =
{
  [1,1] =  0.18730
  [2,1] =  0.076038
  [3,1] =  0.93187
  [1,2] =  0.36252
  [2,2] =  0.74575
  [3,2] =  0.21012
  [1,3] =  0.27078
  [2,3] =  500
  [3,3] =  0.33235
}


which indicates "500".  So the command is properly making its way back to the
core, but the V.E. "a" tab window isn't being updated (which probably isn't
noticeable when all it displays is "[2x2 double]").

Maybe it is as simply as calling "update ()", which is already done with a few
editing operations, but not all.
