打印一个单/多通道矩阵

inline void cvDoubleMatPrint( const CvMat* mat )
{
    int i, j;
    for( i = 0; i < mat->rows; i++ )
    {
        for( j = 0; j < mat->cols; j++ )
        {
            printf( "%lf ",cvmGet( mat, i, j ) );
        }
        printf( "\n" );
    }
}

//举例：打印一个多通道矩阵：
inline void cv3DoubleMatPrint( const CvMat* mat )
{
    int i, j;
    for( i = 0; i < mat->rows; i++ )
    {
        for( j = 0; j < mat->cols; j++ )
        {
            CvScalar scal = cvGet2D( mat, i, j );
            printf( "(%f,%f,%f) ", scal.val[0], scal.val[1], scal.val[2] );
        }
        printf( "\n" );
    }
}
