Hi there.
I am desperately needing a library that can provide me with basic matrix arithmetic.
I am using a MFC VC++7.1 project for which I want the matrix functionality.
I Need:
>> To multiply matrices
>> Calculate determinant of a matrix.
>> Calculate inverse of a matrix.
>> Calculate transpose of a matrix.
I cannot find a library that is plain straight forward to use with VC++7.1 MFC project.
Please refer me to a library that will work for me???
Thanks!!!

Any library that you find with google is almost certainly in use by the authors. You could try reading the support forums to see if lots of other people use it and have trouble, then just choose one and bit the bullet to take the time to learn how to use it.

Yeah, but C++/CLI is not as clear a Managed C++ was, IMO

Yes, it is. I'm just saying that the new name for the forum is confusing.

Hi Raju,
I have a few questions for you !!!! 
1. Which operating system you are using?
2. Are you dealing with multilingual operating systems/system setting
Basically, dialog boxes uses Dialig units(DLU) for creating dialog. So your dialog size depends on the font you are using/char set you are using..
Please have a look at this angle..

The STL provides several container classes like list, map,... and algorithms which cover at least a part of your needs.

Welcome to the real world, kid. This is where you decide to do one of two things
1. Do your own homework, ask questions when you get stuck
2. Apply for a job at McDonalds and move into a trailer park.

Good day,
I have a variable vara, varB.
varA is allocated first. However when I allocate varB due to size, it reaches to the memory area allocated for varA. In this case how can I transfer data so that there will be no memory overlapping which cause access violation error.
Thanks

No way ! If you have allocated memory for varB, when you then allocate memory for variable varA, it will never take memory allocated for the first one. For me it's sound more that you are writing outside the borders of varB and thus writing perhaps in the memory allocated for varA.
Show us the code if you want more help

hello everyone,
i am an application programmer.I have rcently made one package that can calculate arithmetic,combinatronic trignometric functions upto any no. of decimal places. But the problem I am facing is that the execution time increases with the number of digits.This is bcoz I am using auxillary memory instead of RAM.
Can anybody suggest some ways to reduce time delays.
The application is completely made in C++.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Hi,
Is there a free downloadable C++ Class design tool.
I am not looking a complex tool like UML tools. Simple tool which can represent the class and the properties in form of a diagram..
Thanks,

Hi,
I had posted this query in VC++ and C++/CLI forums only.
I don't see anything wrong in this posting, as my query is applicable in both forums and also, some member of either forum may not be member of the other forum.
IF you know of any such tool please let me know..
Thanks,

Hello to all,
i am the beginner of c++ and i wrote some program in Borland C++ 5.0 abt the inheritance this is what i wrote
#include "iostream.h"
#include "conio.h"
class st_Det
{
protected:
int rol_no;
public:
st_Det(){}
st_Det(int a){rol_no=a;}
void put_No(void){ cout<<"\nRoll No :"<<rol_no<<endl;}
};
class st_mark_det:public="" st_det
{
="" protected:
="" float="" sub1,sub2;
="" public:
="" st_mark_det(){}
="" st_mark_det(float="" a,float="" b){sub1="a;sub2=b;}
" void="" put_mark(void){cout<<"\nmarks\n="" subject1="" "<<sub1<<"\nsubject2="" "<<sub2;
};
class="" st_sprt
{
="" score;
="" st_sprt(float="" a){score="a;}
" put_score(void){cout<<"\nscore="" in="" sports\n"<<score<<endl;}
};
class="" result:public="" st_mark_det,public="" total;
public:
="" result(int="" b,float="" c,float="" d):st_det(a),st_mark_det(b,c),st_sprt(d)
="" {total="0;}
" sum(){total="sub1+sub2+score;}
" display="" (void){="" put_no();put_mark();put_score();cout<<sum();}
};
int="" main()
{
="" cout<<"\nenter="" student="" roll="" no:\t";int="" a;cin="">>a;
cout<<"\nEnter Marks In tow subjects";float b,c;cin>>b>>c;
cout<<"\nEnter Score In Sports :\t";float d;cin>>d;
result s1(a,b,c,d);
result.display();
getch();
return 0;
}
but it is giving compile time error like this
st_Mark_Det must be a previously defined class or struct
Regards
cnu...

This is not valid C++, you need to include iostream without the h, and hte include should be in < > instead of quotes.
mcnu wrote:

Where do you get the error ?
mcnu wrote:
class result:public st_Mark_Det,public st_Sprt
I don't think this syntax is correct. I think you need to lose 'public'.
