Hello.
I am using Origin 9.1(Gov).
I wrote multiple functions which take ranges (columns) as vector<double> 's and find things like the derivative, rolling averages on non-static binning, and custom baseline development.
I am fine up to this point where the functions work correctly and speedily(2-4 to find baseline with all inbetween steps).
When using, the functions repetedly, I notice they slow down to about 45 secs after a few re imports original data.
This fixed by saving, closing, and opening the file again. But the real problem is with batch process, where I can see the import take more and more time inbetween. By the way, with Origin's baseline modes, this does not happen.
Should I be deleting my vectors after I use them and if so how...
And how do you make this faster...
Also can you parrallel the batch process?
Nikola

it might be a good idea to post some code that I use
rIx: range In x
rIy: range In y
angles because the binning is un even...
calling something like avgIterAng(rIx, rIy, .02, .02, 12);
can take from 2 to 20 secs... you can try it in a batch why?
vector<double> avgIterAng(vector<double> rIx,vector<double> rIy,
double backAng, double frontAng, int iter)
{
rs = rIx.GetSize();
vector<double> rO(rs);
for(int j = 0; j < iter; j++)
{
for(int i =0; i < rs; i++)
{
double sum = 0.0;
int backPt = -1, frontPt = -1, tracker = i;
//-1 because the first condition in while
//looops will always pass
while(tracker>-1 && rIx[i]-rIx[tracker]<backAng)
{
tracker--; backPt++;
}
tracker = i;
while(tracker<rs && rIx[tracker]-rIx[i]<frontAng)
{
tracker++; frontPt++;
}
for(int index = i-backPt; index <= i+frontPt; index++)
{
if (index>=0 && index<rs) sum += rIy[index];
else if (index<0) sum += rIy[0];
else sum += rIy[rs-1];
}
rO[i] = sum/(backPt+frontPt+1);
}
rIy =rO;
}
rO = rIy;
return rO;
}

Hello,
Batch Process feature has been improved in Origin 2016
Would you please try our current version Origin 2016 to see the improvement

Origin c Functions Slow Down SIGNIFICANTLY
