Edward:
I reformatted your message below because the original runs together w/o
new lines and so is hard to read.
Matrix support in an hbaseshell looks like an interesting addition but
I'm more interested in getting basic hbaseshell functionality,
hadoop-1375, committed first (smile).
I'd suggest the matrix extensions happen in an issue distinct from
hadoop-1375.

HBase > CREATE m_temp COLUMNFAMILIES('A','B','C') LIMIT=3;
//Create Constant Matrix
HBase > A = Matrix(number_of_rows, number_of_columns, constant);
//multiply a matrix by a scalar in place, A = s*A
HBase > A = A.timesEquals(3);....
HBase > B = Matrix(number_of_rows, number_of_columns, constant);
HBase > C = A + B;....
I intend to provide the following grammars to users.
Processing takes place on top of Hadoop + HBase parallelly.
but... How much does it mean to users to provide this feature of
processing data via user-oriented interface on shell?
If you could give me an opinion on the above question, it would be great.
