Simultaneous Equation Solver finds solutions to systems of
linear equations. It provides a convenient, easy-to-use interface
to simplify setting up a problem, solving it, and exploring the
solution. You can:
•Enter, load, and edit coefficient matrices and up to five
vectors representing different right sides.
•Store the solution as a vector (an nx1 matrix).
•Display solutions as a list of values or in reduced row
echelon form (RREF).
•Solve over-determined systems of equations (systems in
which there are more equations than unknowns).
•Solve under-determined systems of equations (systems in
which there are fewer equations than unknowns).
•Solve systems containing both numeric and symbolic
coefficients.
•Identify whether a given system has a unique solution, an
infinite number of solutions, or no solution.
5. Enter the first coefficient and press ¸. The cursor returns
to the matrix and moves to the next column (right). You can
change the cursor to move to the next row (down) instead in
the
FORMATS dialog box.
You can enter a real or complex value or an expression that
resolves to a real or complex value. You can also enter
symbolic data.
Loading existing data
You can load an existing matrix as all or part of the problem from
within Simultaneous Equation Solver by using either of the
following methods.
The variables used in the
editor need to be defined as
real or non-real numbers.
Coefficient A and Constant b
matrices do not have the same
number of rows.
Memory
Element value must be a
scalar or scalar expression.
Coefficients can contain undefined
variables (variables with no ass igne d
value), but the variable type is limited to
real numbers and non-real numbers.
This occurs only when the matrices
specified from „ 4:Two Matrices A and b
are incompatible sizes.
Simultaneous Equation So l ver requir es at
least 6000 bytes of RAM to run properly.
When the amount of available RAM falls
below this threshold, the application may
display an
Error: Memory dialog box and
return to the Home screen or simply exit to
the Home screen. If this occurs, archive or
delete some variables before returning to
the application.
Only scalar expressions are accepted as
input. When using a variable as input,
verify that it is not a list, matrix, or other
non-scalar expression. Choose a different
variable that is scalar.
