MATRIX CALCULATIONS
This function enables the saving of up to 4 matrices (4 rows x 4
columns) for calculations. Press
m4
to enter the matrix mode.
• Matrix data must be entered prior to making calculations. Press-
ing
[
/
]
will display the matrix edit buffer along with .
Enter the value of each item (‘ROW’, ‘COLUMN’, and then each
element, e.g. ‘MAT1,1’) and press
k
after each. After enter-
ing all items, press ª , then press °2 and specify
matA-D to save the data.
• To edit data saved in matA-D, press °1 and specify
matA-D to recall the data to the matrix edit buffer. After editing,
press
ª , then press °2 and specify matA-D to save
the data.
• Before performing calculations, press ª to close the matrix
edit buffer.
• When results of calculations are in the matrix format, the matrix
edit buffer with those results will be displayed. (At this time, you
cannot return to the equation.) To save the result in matA-D,
press
ª , then press °2 and specify matA-D.
• Since there is only one matrix edit buffer, the previous data will
be overwritten by the new calculation.
• In addition to the 4 arithmetic functions (excluding divisions
between matrices),
x
3 ,
x
2 , and
x
–1 , the following commands are
available:
dim( matrix name, Returns a matrix with dimensions changed as
row,column) specified.
fill( value,row,column) Fills each element with a specified value.
cumul matrix name Returns the cumulative matrix.
Appends the second matrix to the first matrix as
new columns. The first and second matrices
must have the same number of rows.
i identity value Returns the identity matrix with specified value of
rows and columns.
rnd_mat( row,column) Returns a random matrix with specified values of
rows and columns.
det matrix name Returns the determinant of a square matrix.
trans matrix name Returns the matrix with the columns transposed
to rows and the rows transposed to columns.
mat → list 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.
matA → list Creates lists with elements from each column in
the matrix. (matA
→
L1, L2, L3, L4) Mode changes
from matrix mode to list mode.
