Matrix Calculations

uModifying Matrices Using Matrix Commands

You can also use matrix commands to assign values to and recall values from an existing

matrix, to fill in all cells of an existing matrix with the same value, to combine two matrices

into a single matrix, and to assign the contents of a matrix column to a list file.

u To assign values to and recall values from an existing matrix

[OPTN]-[MAT]-[Mat]

Use the following format with the Mat command to specify a cell for value assignment and

recall.

Mat X [m, n]

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

m ................................. row number

n ................................. column number

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

Matrix A = 34

baaK2(MAT)1(Mat)

av(A)!+(  )b,c

!-(  )w

JJ1('MAT)w

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

matrix by 5

K2(MAT)1(Mat)

av(A)!+(  )c,c

!-(  )*fw
