如何应用矩阵????急！！！！！！！

Question

看书上写了一个矩阵类class Matrix
头文件: #include "Matrix.h"
在C++下用 matrix <long, double> p(4,4)可以用在VC6.0下
头文件: #include "Matrix.h"
但是在VC6。0下编译不通应如何使用

Answer 1

STL中没有matrix类的，怎么个不通过法，显示的错误具体怎么说？？

Answer 2

以下是在VC6.0下编译#include <iostream>
#include "Matrix.h"
using namespace std;#include <math.h>.......void CCReceCommDlg::ProcessData(int length,unsigned char buf*)
{
 。
 
  const double T=0.2;
const double t_ax=1;
const double tx=0.5;
long double s = 0.0;
long double f1[4][4]=
{
{1.0,T,T*T/2,0.0},{0.0,1.0,T,0.0},{0.0,0.0,1.0,0.0},{0.0,0.0,0.0,exp(-T/tx)}
};
long double f[4][4]=
{
{1.0,T,(T/t_ax-1+exp(-T/t_ax))*t_ax*t_ax,0.0},{0.0,1.0,(1-exp(-T/t_ax))*t_ax,0.0},{0.0,0.0,exp(-T/t_ax),0.0},{0.0,0.0,0.0,exp(-T/tx)}
};
    long double q[4][4]=
{
{0.0,0.0,0.0,0.0},{0.0,0.0,0.0,0.0},{0.0,0.0,0.0,0.0},{0.0,0.0,0.0,0.0}
};
long double eye[4][4]=
{
{1.0,0.0,0.0,0.0},{0.0,1.0,0.0,0.0},{0.0,0.0,1.0,0.0},{0.0,0.0,0.0,1.0}
};
long double r[1][1]={4.5};
long double h[1][4]={1.0,0.0,0.0,1.0};

matrix <long double> pp(4,4);
matrix <long double> pp1(4,4);
matrix <long double> xx(4,1);
matrix <long double> xx1(4,1);
matrix <long double> gg(4,1);
matrix <long double> fft(4,4);
matrix <long double> hht(4,1);

。。

Answer 3

error C2065: 'matrix' : undeclared identifier

Answer 4

class matrix //矩阵类matrix
{
typedef matrix<_Ty> _Myt; private:
std::valarray<_Ty> m_Datas; //定义一维数组对象m_Datas size_t m_stRow; //矩阵行数变量
size_t m_stCol; //矩阵列数变量 public:
typedef _Ty value_type;
...........

typedef matrix<float> matrixf;
typedef matrix<double> matrixd;
typedef matrix<long double> matrixld;........
}//这个地方是不是少了个分号???

Answer 5

贴漏了，有分号，程序一加上matrix.h头文件，就出错。

Answer 6

检查该文件头部有没有#include "stdafx.h"语句，没有的话添加。

Answer 7

我也有同样的问题，有楼上的那条语句。
程序见http://expert.csdn.net/Expert/topic/2508/2508011.xml?temp=.9026453
拜托高手！！
