Hi,

here ist one:

#ifndef PROCABI_H
#define PROCABI_H

#include <vector>

class TProzessfaehigkeit {
     typedef std::vector<double>::size_type vec_sz;
     std::vector<double> TMW;
     bool valid();
     double sx;  // sum x
     double sxx; // sum sqr(x)
   public:
    [...]
};

#endif

Thats the Header. 

In the implementation file you need:

using namespace std;
or better 
using std::vector;

and then you can write e.g.:

int TProzessfaehigkeit::calc() {
  
  typedef vector<double>::iterator vec_it;
[...]
}
