Example 1

Checks if defined system is valid:

      // ...
      // y = A*b
      MtxMulLinReg1.A.SetIt(3,2,false,[-5,2,
                                    1,4,
                                    8,0.5]);
      MtxMulLinReg1.Y.SetIt(false,[-2,
                                1,

      MtxMulLinReg1.UseWeights := false;
      if MtxMulLinReg1.ValidSystem then MtxMulLinReg1.Recalc
      else ShowMessage('System not valid !');
