Exemple de sortie écran :
Linear systems with common coefficient matrix.
Ax1=b1
Ax2=b2
Axn=bn
We can write these equalities in this maner.
A|x1|x2|...|xn| = b1|b2|...|bn|
or simply :
AX = b
where b = b1|b2|...|bn
and X = x1|x2|...|xn
Press return to continue.
------------------------------------
We want to find X such as,
AX = b
We can use the function,
gaussjordan : gj_mZ(Ab);
To verify the result you can
multiply the matrix A by X.
You must refind b.
