the matrix and enter values for the matrix elements. In a new
matrix, all values are zero.
Select the matrix from the
MATRX EDIT menu and enter or
accept the dimensions. The center portion of the matrix editor
displays up to seven rows and three columns of a matrix,
showing the values of the elements in abbreviated form if
necessary. The full value of the current element, which is
indicated by the rectangular cursor, is displayed on the bottom
line.

indicate additional columns.
# or $ in the right column indicate
additional rows.
