extra qualification ‘Matrix:’ on member ‘rowTimesCol’

extra qualification ‘Matrix::’ on member ‘rowTimesCol’

class Matrix{

......

double Matrix::rowTimesCol(int i, double *b, int j, int bc) const;

};

定义了一个Matrix类，但编译器编译时报错，

extra qualification ‘Matrix::’ on member ‘rowTimesCol’

在rowTimesCol之前不能有Matrix::,Matrix::rowTimesCol这种写法在

一些老的编译器中可以通过，现在最新的c++编译器一般都不再支持

这种写法了，最好把Matrix::去掉。
