Description:
New Matrix button creates a new matrix window. The
number of matrix and dimensions are written in the
caption.
For example: Matrix 1, 4 rows by 5 columns: 1[4#5].
First digit in parentheses indicates rows and the
second indicates columns.
Solve System button solves the matrix in active
window by Gauss Elimination Algorithm. For example,
linear system:
x+2y+3z+4w=5
2x+6y+7z+8w=9
3x+4y+5z+6w=10
2x+3y+4z+6w=3
Enter this system in matrix [4#5]:
Click Solve System. Result appear in "Result"
window and Result of x,y,z,w appear in dialog
window as:
"X1=2"
"X2=-6"
"X3=11"
"X4=-5"
Result window:
x,y,z,w are represented by Matrix (I) and Result
is represented by vector "b".
b=
There are cases where "There is no solution"
or "Infinite number of solutions".
Gauss Elimination Algorithm can be solved "Step
By Step" option. Go to "Options"
menu and click "Step By Step" option.
Click "Solve System" button and each
step in the calculation will be highlighted in
blue in "Result" window. Press "Enter"
to proceed to the next step.
Determinant button calculates Determinant of
matrix if number of columns and rows of matrix
match.
Transpose button gives the transpose matrix of
the given matrix.
Add/Subtract button adds or subtracts several
number of matrices. Maximum number of matrices
is 9. Dimensions of all matrices must be equal.
Multiplication button multiplies several number
of matrices. Column of first matrix must be equal
to rows number of second matrix. Maximum number
of matrices is 9.
N*A button multiplies matrix by scalar N.
A^N button raises matrix to power N. If N is
negative button calculates invert matrix of A.
Clear button initializes the matrix by '0'.
By Step - Gauss Elimination Algorithm can be
solved "Step By Step" option. Go to
"Options" menu and click "Step
By Step" option. Click "Solve System"
button and each step in the calculation will be
highlighted in blue in "Result" window.
Press "Enter" to proceed to the next
step.
Maximum number of rows and columns is 99.
