Solve()

virtual bool CIccSimpleMatrixSolver::Solve ( icFloatNumber * dXVector, const icFloatNumber * dMatrix, const icFloatNumber * dYVector, icUInt16Number nRows, icUInt16Number nCols )

inlinevirtual

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.
