I'm running the example problem (in Help) for BlockMatrix but don't get the published result. Am running Mathematica 3.0 in Win95.

Here's the program:

<<LinearAlgebra`MatrixManipulation`;

BlockMatrix[{{a, b}, {b, {{0, 0},
{0, 0}}}}] //MatrixForm

The output is...

Out[6]//MatrixForm=
AppendColumns[AppendRows[a,b],AppendRows[b,{{0,0},{0,0}}]]

...which differs from what's in the book (a nicely printed matrix).

Maybe this is tied to the ZeroMatrix problem I'm having: the command is unrecognized. That is, ZeroMatrix[n] doesn't return an nXn matrix of zeros, but rather, returns the command input.

Any ideas? Thanks.

Bruce
