Member Function: Solve

Purpose: Solve for x in the matrix/vector equation y=Mx when M is 3x3 matrix Otherwise return false.

Parameters: -dMatrix is a matrix (M) with nRows x nCols entries in RowOrder -dYVector is a column vector (y) with nRows entries -dXVecotr is a column vector (x) with nCols entries

Return: true if solution was found or false if solution not possible/supported.

Implements IIccMatrixSolver.

      icFloatNumber mtx[9];
      memcpy(mtx, dMatrix, 9*sizeof(icFloatNumber));
      bool bInvertible = icMatrixInvert3x3(mtx);
      if (bInvertible)
        icVectorApplyMatrix3x3(dXVector, mtx, dYVector);
      else
        memset(dXVector, 0, nCols*sizeof(icFloatNumber));
 
      return bInvertible;
