u u u u u To fill a matrix with identical values and to combine two matrices

Use the matrix operation menu's Fill command (3) to fill all the cells of an

existing matrix with an identical value, or the Augment command (5) to combine

two existing matrices into a single matrix.

Example 1

]

X ..................... matrix name (A through Z, or Ans)

m .....................

row number

n ......................

column number

Assign 10 to the cell at row 1, column 2 of the following matrix :

Matrix A =

baaK2(MAT)1(Mat)

aA![b,c!]w

Multiply the value in the cell at row 2, column 2 of the above

matrix by 5

K2(MAT)1(Mat)

aA![c,c!]
