• Press [1] to [6] to define the matrix dimensions.
• Similarly as in the EQN mode, enter all elements of the matrix
Copying the matrix (e.g. matrix A):
• Press
[2ND][4]
(MATRIX)
[2]
(Data)
[1]
(MatA).
• Press [2ND][RCL] (STO).
• Press to determine the copying target: [(–)] into matrix A, [DMS] into matrix B,
[HYP] intro matrix C.
Calculations with matrices:
• Upon the display of the resulting matrix MatAns, press
[+]
or
[–]
and use the
result in the following calculation.
Items of a matrix menu after pressing [2ND][4] (MATRIX):
• [1] (Dim) Select the matrix (MatA, MatB, MatC) and define its dimensions.
• [2] (Data) Select the matrix (MatA, MatB, MatC) and display its data.
•
[3]
(MatA) Enter MatA.
•
[4]
(MatB) Enter MatB.
•
[5]
(MatC) Enter MatC.
•
[6]
(MatAns)Enter MatAns.
• [7] (Det) Enter function for the calculation of a determinant.
• [8] (Trn) Enter function for the calculation of a transposed matrix.
TABLE calculation mode (function table)
Function tables are used in the TABLE mode, press
[MODE/SET UP][7]
. This
mode enables you to define functions and their expression in the form of a
table. To display the function table:
1. Press [MODE/SET UP][7] .
2. Enter the function and press [=] .
3. Enter the starting value, end value, step size, and press
[=]
.
4. The table of values depends on every X input and is related to the output f(X).
Note : For this function, it is possible to use the X variable. The entered values
of the start, end and procedure should not exceed the number of 30 values of X.
VECTOR calculation mode
Vectors can be stored in the vector memory under the names of „VctA“, „VctB“
and „VctC“. Results of calculations with vectors are stored in a special memory
that is called „VctAns“.
Setting the calculator in the “VECTOR” mode: press
[MODE/SET UP]
and
then [8].
Creating vector:
• Press [2ND][5] (VECTOR) [1] (Dim).
• Press [1] or [2] or [3] to determine the vector name.
• Press
[1]
or
[2]
to determine the vector size.
• Similarly as in the EQN mode, enter all elements of the vector .
Vector copying (e.g. vector A):
• Press [2ND][5] (VECTOR) [2] (Data) [1] (VctA).
• Press [2ND][RCL] (STO).
• Press to determine the target of the copying operation:
[(–)]
in the vector A,
[DMS] in the vector B, [HYP] in the vector C
