1. How to compute system of the three linear equitions ?
Suppose this three linear equitions (Ax=B):
Use this code for calc solution:
/* degree=3 */
PICramersRule cramersRule = new PICramersRule( 3 );
/* set A side coeficients */
cramersRule.Get_matrixA().AddValues( new int[] { 1, 2, -3, 2, -3, -5, 1, 1, 1 } );
/* set B side */
cramersRule.Get_matrixB().AddValues( new int[] { -9, -8, 4 } );
/* calc */
int i = cramersRule.Calc();
switch ( i ) {
case -1:
Console.WriteLine( "Some error." );
break;
case 0:
Console.WriteLine( "System of linear equitions has no solution." );
break;
case 1:
Console.WriteLine( "Result = " + cramersRule.Get_results().AsString( 0 ) );
break;
}
Output:
Result = 2;-1;3
Roots of the three linear equitions are -> x1=2, x2=-1, x3=3.
