Using Matrices in Calculations

Matrices stored in memories (matA–matD) can be used
in arithmetic calculations (with the exception of division
between matrices) and calculations that use
−
x
1
and . You can also use the following matrix-specifi c
functions that are available in the MATH menu.
dim (matrix name, row, column) Returns a matrix with
fi ll (value, row, column)
cumul matrix name
aug (matrix name, matrix name) Appends the second matrix
identity value
rnd_mat (row, column)
det matrix name
trans matrix name
mat→list
( N 7 )
matA→list
( N 8 )
Notes:
• When the matrix entry screen is displayed, you
cannot perform matrix calculations because the
MATH menu is not available.
• If the calculation result is a matrix, it will be displayed
in the matrix entry screen (note that this replaces any
existing data in the buffer). To store the calculation

Fills each element with a
specifi ed value.
Returns the cumulative matrix.
to the fi rst matrix as new
columns. The fi rst and second
matrices must have the same
number of rows.
Returns the identity matrix
with specifi ed value of rows
and columns.
Returns a random matrix with
specifi ed values of rows and
columns.
Returns the determinant of a
square matrix.
Returns the matrix with the
columns transposed to rows
and the rows transposed to
columns.
Creates lists with elements
from the left column of each
matrix. (matA→L1, matB→L2,
matC→L3, matD→L4)
Mode changes from MATRIX
mode to LIST mode.
Creates lists with elements
from each column of the
matrix. (matA→L1, L2, L3, L4)
Mode changes from MATRIX
mode to LIST mode.
