After you have set the dimensions of the matrix, you can view 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.
This is an 8 × 4 matrix. Ellipses in the left or right column indicate additional columns. #
or $ in the right column indicate additional rows.
