why does initialise with vector not work here ?

[Matthias Pospiech]

This class:

#pragma once
#include <vector>
#include "um.h"

#define MAXMROOT 9 /* 2^(MAXMROOT-1) = # of elements in BRcnt */

class FastFourierTrans
{
public:
FastFourierTrans(void);
~FastFourierTrans(void);

public:

void FFT2D(vector<vector<CComplex InputArray,
vector<vector<CComplex OutputArray, long N,long sd);
};

throws the following error i do not understand:

1>e:\daten\dev\cpp\lightmodulator2dmat\lightmodula tor2d\FastFourierTrans.h(34)

What is wrong ?

It seems that the error message from compiler is not in English. SO,
could you please translate the error message to English?

Either use 'std::vector' or add 'using std::vector' before this class
definition. BTW, what book are you reading that doesn't explain 'std'
namespace and how it's to be used?

'vector' is undefined. Next time please translate the error message into
English -- this is an English speaking newsgroup.

My German stinks -- but my guess is you need

std::vector

[*PaN!*]

"Matthias Pospiech" <ma********@gmx.dewrote in message
news:f1**********@newsserver.rrzn.uni-hannover.de...

void FFT2D(vector<vector<CComplex InputArray,
vector<vector<CComplex OutputArray, long N,long sd);

Use std::vector.

btw, i'm not sure it's a good idea passing two, possibly big,
vector<vector<X by value. In particular, it's not a brilliant idea if one
of them is supposed to be modified by the method (and you really want the
result to reach the caller).
I'd use a const reference and a simple reference respectively.

I don't understand your language, but it seems you are missing
'using namespace std' or you can try 'std::vector' when you use vector
in your code.

Use std::vector.

Yes, of course. I know why I need it, but id did not came to my mind...

You are absolutely right. I have changed it.
