vectors

[Genia]

Guys, i have two codes that fill up vectors and then afterwards another piece of code should use the numbers in vector for further processing. When I use 1st code data is processed and I get expected results, but when I am trying to use 2nd code, subsequent function returns the same number as it gets without processing. I guess that it might be related to the way I save data into vector, but I have no idea how to fix it. Any help will be greatly appreciated!

1st code:
  for(int i = 0; i < new_n; i++)
	{
        Deriv[i] = Deriv[i] / m_max_1;
		if(Deriv[i] < 0.100)
			Deriv[i] = 0;
		if(i < 8)
			continue;
		else
		if(Deriv[i - 1] > Deriv[i] && Deriv[i - 1] > Deriv[i - 2])
		if(!peaks.empty()) //checking whether this is peak or not
		{
		    bool moreThenZero = true;
		    bool Zero = false;
		    for(int j = peak_pos.back(); j < (i - 1); j++)
		    {
			if(Deriv[j] == 0)
			{
			   Zero = true;
			   break;
			}
			}
			if(Zero)
			{
			peaks.push_back(Deriv[i - 1]);
			peak_pos.push_back(i - 1);
			peak_posD.push_back(new_arr[i - 1][0]);
			}
				}
				else
			if(peaks.empty())
			{
			peaks.push_back(Deriv[i - 1]);
			peak_pos.push_back(i - 1);
			peak_posD.push_back(new_arr[i - 1][0]);
			}
    }

2nd code:
for(int i = m_max_2; i < new_n; i++)
	{
        Deriv[i] = Deriv[i] / m_max_1;
		if(Deriv[i] < 0.100)
			Deriv[i] = 0;
		if(i < 8)
			continue;
		else
			{
			for(int j = i; Deriv[j] > 0; j++)
			{
  if(Deriv[j] > Deriv[m_max_2] && Deriv[j] > Deriv[j + 1] && Deriv[j] > Deriv[j - 1])
			{
			m_max_2 = j;
			}
			}
			}
			if(Deriv[i] == 0 && Deriv[m_max_2] > 0)
			{
				peaks.push_back(Deriv[m_max_2]);
				peak_pos.push_back(m_max_2);
				peak_posD.push_back(new_arr[m_max_2][0]);
				Deriv[m_max_2] = 0;
			}
    }

We're missing a whole lot of context.

When posting code, please make sure it is a minimal but compilable snippet of code that (still) reproduces your problem. Preferably with a better description of the problem than "some other code doesn't work when I use this."

Here is the code that i use to process the dara from peak_pos vector:
int UnknownGe::set_up_lim(int k)
{
int j = peak_pos[k - 1];
while(Deriv[j] > 0)
{
j--;
if(Deriv[j] == 0 || new_arr[j][0] < 2)
break;
}
if(new_arr[j][0] < 2 && Deriv[j] > 0)
return (j + 1);
if(k == 1)
{
if(new_arr[j][0] - new_arr[0][0] < 10)
return j;
else
return (j - 2);
}
else
if(peak_posD[k - 1] - peak_posD[k - 2] < 10)
return j;
else
return (j - 2);
}

and this function is supposed to find a point, in Deriv[j] array, which contains 0, and when it gets value from the 2nd code, it returns the same value as it gets, while using the 1st code it returns expected value.
