Displaying the contents of a matrix



Hello!

Consider, I have a matrix A, which is created using

A=matrix([1,2,3],[4,5,6],[7,8,9]);

How can display the contents of the matrix, that is to get the output 

[1,2,3]
[4,5,6]
[7,8,9]

?

I've looked in the docs, but the suggested commands (DISPLAY, for
instance) did not produce that output.

TIA
