SLAE Solver User’s Guide
SLAE SOLVER allows to find on a PDA high accuracy solutions of linear algebraic systems with N equations.
Notations: A(N,N)- matrix of coefficients, B(N)- vector of coefficients, X(N) –unknown real variables of a system A(N,N) x X(N) = B(N).
1. Entering Data
i. Entering N, dimension of the SLAE.
Enter N into the box “N” (Number of Equations).
ii. Entering A(i,j),i,j=1,N,coefficients of the SLAE (elements of the matrix- A)
1. Select the first index –i of an element A(i,j).
2. Select the second index –j of an element A(i,j).
3. Enter the value A(i,j) into the box “A(i,j)”.
4. Click on the “Accept A(i,j) “ button.
iii. Entering B(i), i=1,N elements of the B
1. Select the index –i of an element B(i).
2. Enter the value B(i) into the box “B(i)”.
3. Click on the “Accept B(j)” button.
To view the system click on the "Show System" button
To return back click on the "Back" button.
2. Finding a Solution (the data must be entered before you start this step)
Click on the “Find Solution” button
The solution will be shown with a rounding error.
To impruve the current accuracy of the solution click on the "Improve" button.
